Hum, #open has to go somewhere, so...

Either it goes into a sort of Application Model, which regroup the 
duties associated with the application (the view + model + whatever is 
necessary in environment X), or it goes into an Application View which 
then has model concerns in it (it knows how to start or connect to the 
model, it knows what the model is composed of to connect subviews to 
model elements, etc...).

I prefer to model an Application concept in the target desktop 
environment if I want to model highly portable stuff.

That application concern can be folded into a dedicated view if that is 
the preferred convention in the target environment.
