I wouldn't call this "real MVC", these (very elegant) Seaside like  
state machines are something built on top of the MVC pattern.

The main problem of state machines for webapps is that they are  
limited to (plain old) multi page wizards, it would be a mess to use  
them in "modern" more dynamic apps using things like AJAX.
But as i agreed with Autrijus, state machines are a nice backup  
mechanism for browsers that don't do AJAX or apps with a special  
requirement for accessability.
I can imagine having such hybrid systems for higher level widget  
toolkits.
