It might work, and does sound like it has some cool advantages.  I see a 
couple of disadvantages, the foremost being that this would force a property 
set solution on someone wanting to implement this: I'd like a simpler 
solution from which one could build a variety of "helper" solutions, some 
possibly using property sets, some using formulator, some using sessions and 
temporary objects, and so on.

I just took another stab at this on the wiki--also not fully thought out, but 
it seems like a start.  David, I also linked to your email.  Feel free to 
trash what I wrote about it and explain away, or whatever you want.
