Interesting idea.

But does ModelDriven provide any benefit for this?  Couldn't you do the 
same thing in a normal action getter (that returned an interface your 
various model flavors coded to)?  And in that getter (instead of in 
getModel) you'd do your switching logic?

I'm still not seeing any advantage to ModelDriven (although I find that 
particular take on providing a model pretty cool).
