   binding between model objects isn't recommended at all. the bindings 
doc is clear about how we recommend doing it (controller to model, 
view to controller.. it would be useful to extend that to the 
occasional view to model as well though, I'll add it to the list). 
We don't say how we don't recommend doing it in general though..
