A quote from Novell: Demonstrating Inter-company Collaboration
The Google Wave Federation Protocol excited us, because for the first time since email, it provided a way for collaboration systems to cooperate in a non silo’d way . The promise is that each organization can choose what product to use and the communication will flow unimpeded between the different systems, in the same way that people on different email systems can send and receive messages to each other today. This is a collaboration revolution we wanted to be a part of. - “Novell Pulse and Google Wave” - Google Wave Developer Blog.
This is exciting. More detail up soon.
