Take an existing p2p app like

Gnutella. Add some sort of metadata

to the id3 tag, like "copyrighted: no"

and then use it to distribute and find

uncopyrighted music.



Give users the ability to rate songs or

mark them as illegal copies.



Eventually, people just start sharing

tons of good, free stuff.



Oh, and I want it to have some sort

of collaborative recommendation

engine. And a puppy.
