Hm. Something to watch. "XMPP PubSub is (part of) what makes collaboration work in Sugar as well, and that's got its own scaling issues on a school server. It isn't the "how do we handle hundreds of thousands of users with a rack of blades (or whatever)" problem, but the "how do we maintain very chatty collaboration between hundreds of kids on an inexpensive school server that's also doing 10 other things at the same time" problem." Also, "XMPP Pubsub is also the best route to a modern, open source SIF implementation (not that I expect to ever see one)." XMPP stands for 'Extensible Messaging and Presence Protocol' and is what became of the original Jabber messaging protocol. PubSub is the XMPP XEP-0060: Publish-Subscribe protocol.
