Yes - I've put a lot of work into this (inspired by mark's demo).  
What I am thinking would be a good demonstration of how MVC can add  
to the collaboration possibilities inherent with Revolution is to  
release this for a tree widget.

There are several different versions and data models for outliners /  
tree widgets floating around and by adding an MVC architecture the  
developer can not only customise a single tree widget for many  
purposes, but also switch between data models.

This gives other developers the ability to fork / improve the speed  
and robustness of the implementation by cloning or creating a new  
data model (while still using the same tree widget view). It also  
allows users to easily switch / upgrade to alternative data models?
