Reader Guaranath brought my attention to a video showing off some Max 4 Live (Ableton Live) experiments.
ORQUESTRA ELECTRÒNICA DEL VALLÉS, ooeevv if you're nasty, has been working on collaborative networked-music-making. In this example they've got 4 laptops all playing together. They've obviously spent a lot of time thinking about how people would use this, as they've even included chat inside of Ableton! That sort of functionality would make more sense if their aim is to make this possible over the Internet, rather than this example in the same room with an evil coffee maker.
This is barely relevant to the site, but I swear you can see an iPhone twice! It looks to be running a custom "OEV" app, so this could be a hint at things to come.
