Interesting that in such a short article they mention Rendezvous. It will be interesting to see how they actually implement this. I have looked over the Internet Draft, and have not figured out how they do cross-router locating of resources. Rendezvous seems like Appletalk functionality with IP. The problem will be if it interferes with corporate networks, it will get squashed.
I need to see if anyone at work went to WWDC and got the disk to try it out.
