I'm in about the same position as you right now - trying to learn 
formal object modeling and ZPatterns, so I'm not qualified to say 
anything about your model or questions... I just want to mention two 
things that I found:

- I didn't find any of the modeling tools you mentioned, or others 
I've tried, very useful on a Mac (or at all), and I ended up using 
ConceptDraw, which is a general purpose drawing tool with UML and 
Coad libraries.

Very true, IMVHO. I still find there's a big gap between a Coad model 
and a ZPatterns implementation, but it's much better than with UML.
