I like this comparison to MVC. Views + a state machine is basically a description of CouchDB and CouchApp style programming, so I've seen the OPs architecture being used in very real life situations. I've been calling it an event architecture, that that's not a great name. It's not just events, because events can cause the client to query, so there has to be a whole state machine backing up the event system.
