Just to clarify this:

   I'm not suggesting that the controller's responsibility includes 
validating data.

Rather, I mean that you can use SkinScript to easily add an "aspect" of 
validating data in a certain way. In MVC terms, this is like a wrapper 
around the model that validates the data. All connectors from 
controllers to the model must go through this wrapper.
