Who, What, Why?

I'll provide a separate tutorial on configuring a surface as a media player, and also how to script the media. Scripting is already there with new functions to read the currently displayed URL and set w new one, as well as changing other settings. Importantly you have good control over who can interact with the media, and this too is scriptable. You can also create and manipulate a whitelist of acceptable URLs - you don't want vistors leaving nasty suprises on the browser. The other thing you can do of course is script the panel to reset and return to it's homepage if there's no one near it.
The new UI supports several features to help interact with the new media features. When your mouse hovers over a media surface, a small icon bar pops up allowing you to enter a new web address, or go forward/back/home. At this point, the media surface does not have focus. However, if you left click on the surface, a faint green outline appears. It now has focus, and your keystrokes now go to the browser. In addition on the popup navigation bar there is a magnifying 'zoom' button - pressing this zooms and centers the surface for easier viewing.
If the surface is configured to display Quicktime-playable content, a different navigation bar appears, with volume control and elapsed time display
This new shared media functionality is provided by the new SLPlugin architecture in the viewer. SL Viewer 2.0 comes with 2 plugins, one for displaying web pages and one for Quicktime. The plugins launch as separate processes, on a windows machine you will see up to 8 SLPlugin.exe processes running. There are already other plugins being worked on, including one that supports VNC desktop-sharing protocol and since the API is public, the expectation is that people will develop more. Mind you, with the full browser support now available, a huge raft of possibilities open up even without new plugins - shared whiteboarding and collaborative reviewing and editing being the most obvious to me.
This really is going to make a huge difference to what can be done in SL, certainly for enterprise and education uses. Along with all the other changes in Viewer 2.0 this has me all fired up about SL again. Great work!

When we first formed Flying Island we would hold regular skype conference calls. It was useful (and free) but frustratingly clunky to use. If one party dropped out, as they regularly did, more often than not we'd have to restart the entire call. Sometimes I'd try to reconnect, only to end up in a one to one conversation. If some colleagues were already in a group call, I couldn't just join in. If we'd been in the same physical space it would have been so much simpler - just walk up to the group of people you need to talk with, and start talking... shouldn't a conference call be as easy?
The voice chat integration in SL gets slated but my experience has been overwhelmingy positive. The niggles that are there should hopefully be removed with the auto-level adjustment and echo cancellation that are due to be part of the Viewer 2.0 release in March. The huge 'aha' moment for me happened after a Show and Tell gathering at the Beta Business Park in SL - around 10 of us had been voice chatting, swapping our best discoveries of the previous week. When the meeting broke up, I noticed that some of the Flying Island founders were online in the office on the park. I walked my AV across the park and into the office, as I entered I could hear them talking, and I simply sat down and joined the meeting. Effectively I'd gone from one 'conference chat' with 10 people to another with 3 other people in exactly the same way I would have done in a physical space - by walking from one group to the other. No menus, commands, connections to negotiate, it just worked. The voice integration has other nice features too. Working out who is talking is quite natural, helped by many mechanisms built into the environment - spatial cues with the sound appearing to come from the correct place relative to your field of view, glowing 'vu-meter' above the speaking avatar and various animations during speech. Also, if you need privacy then lock the parcel of land you are on to prevent unauthorised access, and restrict voice to the parcel.
I should say that the VoIP in SL is provided by Vivox and it will be interesting to see what innovations the recent announcement of another $6.8m of funding for Vivox might bring. The transparent metaphor of forming chat groups by proximity of avatars within the virtual environment isn't confined to SL, it is true of many platforms and games based on Vivox or similar spatial voice servers. But it is a perfect reminder of how the use of 3D immersive spaces populated by avatars can make collaboration much more natural.

Ironic. A day after discovering this glowing oracle-branded summary of the amazing immersive collaboration platform that Sun had put together in Project Wonderland, the Wonderland developers tell us that Oracle have pulled the plug. They are putting a brave face on it - it didn't exactly come as a total surprise to the team or indeed anyone else - like most Virtual World developers, my heart sank the day Oracle bought Sun. Some of the existing team hope to create both commercial and not-for-profit enterprises out of the ashes, citing a few existing Wonderland commercial developers as proof that there is something to it. Well, there's certainly something to it technically at least. Unlike Second Life and OpenSim-based enterprise collaboration systems, Wonderland was designed from the ground up as a serious work environment, specifically to solve the problem of allowing employees who were out of the office to continue to interact with their colleagues just as if they hadn't left. The telephony features alone are really tremendous, and by leveraging the existing X-windows protocol, there is proper built-in application sharing with OpenOffice documents, whiteboards and web-browsing. This means real server-based shared web-browsing where I see what you see, not the Linden Labs style embedded browser client coming in SL Viewer 2.0 that is different for each viewer. What about dragging and dropping documents and resources from the desktop straight into a meeting? Yes, that's there too. The graphics have been criticised quite rightly in the past, but the 0.5 release leaps into far less cartoony territory, and looks ready to start creating a convicing sense of immersion. Both server and client are built on java, so there is a massive base of developers round the world who could get involved and development tools and environments for java are fantastic. If there's anything missing technically it's probably rich gesture animations and voice gestures/lip sync, and a browser based client. But technically, it looks great.
The problem is that like OpenSim all the intiaitives and developments around Wonderland have been technical. It is geek heaven. But if a potential enterprise user read the glowing summary and thought "Wow this sounds useful. Where do I start?" they would have a mountain to climb. What seems missing is the business perspective,the return on investment arguments,the convincing real world enterprise success stories. Also needed is a way to jump into a Wonderland world and start experimenting with it straight away, preferably in a private space you could invite a colleague to with a clean simple interface and good help resources in the form of newbie training videos and orientation, or even people available in the space to help you. The Amphisocial folk have to be given credit here for creating something that integrates Wonderland into a web platform for launching meetings and collaborating, and at Flying Island, the company I work with, we are also looking closely at Wonderland as part of our collaboration solution.
So I really hope that the team can put something together and I hope that it has a serious business focus. I'm really looking forward to the 0.5 release and a roadmap for the future, and that the promise of Wonderland is fulfilled.
