Some company jumped on apple's ass for their networking technology that they had called rendezvous. Still, "Bonjour" is a pretty bad alternative for the name. They might as well have gone with calling it "Howdy-Do" technology.
Tibco own the Rendezvous name. I've used their software myself. It's popular in the stock trading world and is kind of like what Apple meant by Rendezvous to boot.
