I'm not sure how to go about implementing this, but some thoughts I've 
had about MVC in wxPython are that it would be nice to be able to have 
some sort of modular controller and/or model.  In other words, each 
widget involved in the view would have an associated component that 
would automatically integrate itself into a composite controller or 
model of some sort.  Then there would be a standard but flexible way to 
hook that to the application's model.  This would allow the app model to 
be whatever it needs to be for the app or the programmer's preferences, 
and just use a flexible but well defined interface for communicating 
with the rest of the system, which was all built automatically based on 
how the UI is put together.
