I dreamt of an idea!

[DeezNotes]

Yesterday, I dreamt that I was collaborating with someone here and we were both working on the same song at the same time, just like on Google Docs (i.e. I could see which notes he was clicking on, what he was editing, etc. in real-time, and while we were chatting on the side).

Wouldn't it be cool if that were possible on OS?
