I dont think you'd really have to host all the music, although I agree it would be nice. I do my advocacy bit here : http://www.em411.com It's a really nice site and great community - they even put up with linux nutters there :) Anyway, they don't host the members music, just provide a way to let people know you have releases availible, and allow people to comment on them. It works well. They also do remix competitions, latest software announcements (I put the last ssm release there :) ) and general forum banter. If a specific linux based musician's site was set up, I'd contribute, definately - but I also think it's good to mix with people who write music on other OS'es too - it can be enlightening to compare the differences (it's not all easier on windows/mac these days) dave
