Steve Gillmor via Hack the Planet:
Now if we can get Apple to open up Rendezvous across the Net.
From what I recall, Rendezvous is completely open. You can download Apple’s reference implementation at their website under the Apple Public Source License. All the information is at the Rendezvous project page. Also of note is the Rendezvous developer page. It’s also known as ZeroConf outside of Mac circles.
Rendezvous is open indeed.
