I don't think Windows fully supports Rendezvous (or ZeroConf as the rest of the world calls it)... but if I have 2 or more ZeroConf machines, with no network settings at all... on the same physical network (ie a simple hub or switch) they will all be able to connect to each other on an IP level with NO setting up.

Rendezvous/ZeroConf isn't just a fancy way of sharing stuff, its a way of automatically configuring networks... so no, you havn't HAD to spend time getting your machines on a network.

As soon as Windows gets true ZeroConf support you'll see a lot more of this.

What do you think of that T-Shirt on Wil Wheaton 's site, with the name tag, "Hello, my name is William Fucking Shatner".
