Thanks for the discussion, all!  I believe we've agreed that "many 
feedback loops may be interpreted" through the  model.   I've updated 
the wiki page to reflect this agreement: 

I'm starting a new email thread on using that in our literature review, 
look for that soon.  I think I'll start a new wiki page also.
