Isn't this pretty much what I said in an earlier post?

I don't buy this. A machine wants a service, a human wants an interface it
can interact with. The UI for the human may use that service, but in an
MVC sense the service is providing access to the model, not the view.

Gee, that is a bit user-centric. Classic design also calls for a business
tier and a data tier.

Why? Because all the complication is in the Javascript library?  I still
want to know how you are going to handle data that cannot or should not be
stored in the user's browser? The argument that there isn't any (which you
haven't made) just isn't the case.

No offense to Stefano, but I don't think he has ever worked at a bank. 
But yes, Cocoon should easily be able to handle this.
