Absolutely agreed, I'm currently experimenting with a double-layer MVC 
approach where I have one MVC for the domain model and the app itself is 
a second MVC whose model merely interacts with domain view and 
controller objects (for those of you following along the "stealing from 
Jifty" part, this is not unlike the Jifty action approach although Jesse 
and I can probably claim "parallel invention" rights given we've been 
discussing this sort of stuff for close to a year now).

The nice thing about this approach is that provided you present the 
appropriate domain view/controller interfaces you can swap out the 
underlying implementation trivially since your DBIx::Class or similar 
objects never leak outside to the UI/web layer.
