NSViewController manages a view, which can be loaded from a nib. When 
you instantiate one, you've got a view controller and a view out in 
space. Where would you like it to hook into the responder chain?

I wrote the functional equivalent of NSViewController for an app 
deployed on Tiger. When the view is inserted into the window, I hook 
the view controller into the responder chain at the appropriate point. 
When I remove the view from the window, I unhook it. The same 
technique should work with NSViewController.
