Anyone using it? It's in its infant state but there might be some light there.
Today I found a gadget/robot[1] that actually lets you collaborate by writing
music score. Sort of useful. Definitely not for advanced users of music
notation. Not yet anyway. But when your sitting down together and trying to
communicate a riff or similar it might be handy.
I think for collaborative score composition the best way would be 'off line' (i.e. not realtime).
Agreeing on the exchange format for the sharing is another story :)
