Yeah, it can just be considered a free collaboration pool where anyone can upload a spare keyboard track or whatever and others can then download and add their own audio to reshare with the group.
It would be nice to keep it semi-organized so it's not an instant mess. I'm thinking everyone should use some sort of name (fake is fine) per song for communication's sake and preferably include helpful info for potential collaborators (tempo, key, comments) in a text file zipped alongside the audio.

We should get a game of TF2 going for folks in the Steam group soon. My wife will play too, though she may be lost if we're not on 2fort or Turbine.
