I use dropbox to collaborate with my band while we're making music remotely. It would be wonderful if there were more tools to support this. Even simple things like being able to stream music on the go, the media player in dropbox isnt very good. Id like to able to listen to multiple songs in a folder one after another, without having to go back and click again on the next one to load. More of a multi song media player
Another idea, Your team should look at Splice, and how their remote collaborative tool works for Ableton and other music DAWs.
