We have always (as land owners) had the ability to set video parcels in Second Life. This has of course been a bit of a pain with only one video stream, or web page display allowed per parcel. Now we have new media sharing abilities. This has already been implemented in some of the other platforms, but most of those are less user generated in their content.
I tried a few extensions out to ideas, in particular powered by the fact that SL will play interactive flash now not just flash movies as before.

I used a mind map tool on the web and mashed it with wearing a sphere for a presentation. i.e. you can wear interactive web applications now
I dropped myself into a flash based flocking display where I controlled the direction of the fish.
Finally I popped into Habbo Hotel.
There are of course a few issues and gotchas with interacting with flash. The experience is not totally shared. The browser URL is shared, but not all the interactions. This is only to be expected. I am not complaining, but I know that this will confuse some people. A web interface is inherently single user even if there are multiple users of a system.
Loggin in and personalizing your view of a system is not going to change others views unless the controlling website knows whats going on with this virtual world and multiple users hitting it in context.
There are a lot more things we can do now though, website based HUD’s(I have a transparent twitter hud on right now), textures stored off world (though we are limited to 8 player surfaces at the moment so this could get clunky).
With the combination of SL being able to create HTTP Server objects too we have quite a loop of connectivity.
This is very exciting stuff as many of the projects over the years that I have been involved in move data around and in and out. Things got a whole lot easier I think.
