Rendevous?

[neoelectronaut]

You know, I'm watching the '04 Keynote, and I'm about halfway though. I noticed that Steve tends to mention Rendevous alot throughout the keynote. I know it's some sort of messaging service or something, but what exactly does it do, and should I be using it?

Apple can explain it better than any of we can. (http://www.apple.com/macosx/features/rendezvous/)
