Yeah it sounds pretty interesting. It works off of the idea that you can lend your music to a friend, and you can make a backup of something, what you can't do

Yeah it sounds pretty interesting. It works off of the idea that you can lend your music to a friend, and you can make a backup of something, what you can't do is listen to your backup while the other person listens to the original. So they let people 'upload' their songs to get a number of keys and then when you want to listen to a song, whether you own it or not, as long as there is an available key it should be legal. If it holds up I would LOVE to see this for movies and TV shows.
