I have an idea that probably doesn't have much revenue generating potential but it could be a cool new feature (to me at least). I spent about 20 seconds on the website so sorry if you already have this, but I didn't notice it. The users could have the ability to do interactive jam sessions, even if they are miles apart. Maybe something like a high fidelity audio only version of Google Hangouts.Each participant would need some headphones and a resonable quality microphone. I guess if you were looking for a way to squeeze some money out of this, perhaps you could sell recorded copies of the jam sessions to the participans or anyone else willing to pay for them I guess. Sorta like a demo mixing service :P I bet a lot of bands could get their start this way. You'd be removing any limitations of proximity between musicians. Can you imagine if every member of the Beatles had been born in different parts of the world?
