Yeah, the hack you describe is essentially the one we use here, and
it works rather nicely.  Yes, it makes the world into two (or more)
big program, emacs plus a command interpreter (the shell in unix).
This still requires that all window management, editing, and buffer 
management be lumped into one program (emacs), and that people
who wish to use another editing command structure use another version
of emacs, for example, one that use vi command conventions.

This in fact may be the way to go.  But if so, I would like not to
back into it, and have some understanding of what it implies.
