Has anyone out there experimented with a large number of 
concurrent MVC triads?  Our group is putting together a tree browser,
and would like to have an individual pop-up menu for each node in the 
tree.  The cleanest way to do this would be to have a separate view and
controller for each node, but with 20-50 nodes being shown in a window
at any one time, I am concerned about performance. 

Given this, which is better--50 very simple controller-views, 
each handling its own node, or one complex controller-view that can 
handle the entire tree?  What kind of overhead is involved in adding
extra controller-views?

Thanks in advance,
   -Ron
