I've seen a different use case for XMPP that I thought was interesting. Basically, a public-facing site uses it for running customer support chat bots, providing FAQs and the like. Under the hood, initiating a chat is basically launching an in-browser client over WebSockets, and spawning a "chat room" with a dynamically-created bot. Maybe this is common, I don't know, but seems to work well.
