Looking for community input on my 20x20 talk

I'm looking forward to the November 2010 20x20 event.  My presentation, about (broadly) collaborative learning in an Extension environment, will push me into some new terrain.  I've posted some early thoughts and a work-in-progress outline, and I'd love some help making it the best it can be.  You can see the concept, and share your ideas, links, thoughts, criticisms, or whatever else, at http://esagor.posterous.com/early-thoughts-on-my-presentation-at-20-by-20.
