If there is something cool about Zune is the possiblity of share music "adhocly" through wifi. Of course there are a lot of limitations and that is what sucks so much about Zune. Well, my idea is simple: share music wif a friend within wifi range. I'm aware of how dificult the development would be, but you must agree that it would be one of the most sweet applications around. Imagine the user interface beeing something like this: When two (or more) freinds connect to each other, his playlist would appear as coverflow. A simple tap on the album would turn its back and a tap on the song would copy it. What you think about it?
