We tried our hardest back in the early 2000's to make this stick. I cofounded a startup building servers, clients, and SDK's. Maybe the world is finally ready for it now. The issue we ran into was customers/consumers just didn't care about federated systems. And various implementations had all sorts of quirks making interoperability between domains and clients difficult, at best. There are just SO MANY THINGS you have to do to make good messenger software that lining up all the pieces with open standards proved impossible in the ~8 years I was working on it. Again, maybe it's better now, but I'm skeptical, probably jaded. :)
