Well, when I open iTunes on my laptop on campus I see a dozen or so shared music lists on the network. If you want to share your music with the cute girl in the coffee shop it would be easy as pie with an iPhone - as long as you're on the same network. Good point, but remember, iTunes will not stream ANY song purchased from iTMS unless the receiver is one of the four other computers authorized to play it.

"Sector does not found"
A former boss of mine was an Ornamental Horticulturist before he became interested in computers. He designed golf courses!
