A couple of times I've tried somewhat seriously to build "google docs for ableton" (meaning two people editing the same project on different computers, seeing each other's edits in realtime). Frustratingly I decided it was impossible to do a really good job of it back then. This sounds like it might finally make it doable!

We should talk - I'm building a new DAW with this in mind :)

Don't kick yourself. It's not possible with Google Docs either. All these collaborative document editors have been mostly gimmicks/wastes of time.
