I guess it depends what you mean by "model." In Morphic, for example,  
morphs have a "model" ivar that points to a class like Browser, but  
Browser is really a model *of the UI*, not the thing that the UI  
manipulates. That is, the PluggableListMorphs in a browser don't  
connect directly to a class or a or a system category. The Browser  
mediates between the views and the domain objects. If by MVP you just  
mean that the views communicate with an object that mediates between  
them and the actual content of the UI, then Morphic and Tweak are  
both instances of MVP.
