iTunes 4 Sharing Beyond Rendezvous

So Apple’s done a zillion announcements today; the one that hits me the most obviously is the iTunes 4 one.
Rendezvous sharing is very cool, but in fact, Apple will allow you to share with anyone, so long as you have the IP.
Just go under Advanced, hit “Connect to Shared Music”, punch in the IP, type in a password if the user has one set up, and it’s just like they’re on your LAN.
It’s streaming only, but it’s very good streaming. Even album art comes over (which I’m furiously tagging my MP3s with). I only had to rebuffer twice playing the Beatles’ “And I Love Her” from a friend in California.
Edit: Apparently the friend who said the album art came over was on crack. Oh well.
Nicely done, Apple.
