Ugh.  OK, I'll take a look at it.  (Hurry up Climacs...)

I'll check - Jay, does Emacs allow that kind of dynamic, context
sensitive key binding?  I MIGHT be able to put together some sort of
hack but an Emacs supplied mechanism would be better.

Actually, I might get the undo binding to turn it black.  Good point. 
I don't view the turning red on alteration of input as trivial - it
avoids the situation where someone was going to make a change, forgets
to evaluate it, and then prints something that appears to show
incorrect output.  As for the "notebook", I have always been frustrated
with accidental "wiping out" of input prompts and other structures that
users shouldn't be editing.  I think, give or take the bugs, I am
content to leave it pretty much where it is (your output marking
feature I can take a stab at) and move on to the more advanced LaTeX
based features.

OK, I think EMaxima provides an example of that.

I suppose.  Since my idea for Doing It Right doesn't involve Emacs
anyway I suppose being pragmatic wouldn't hurt...

OK, if there is interest I'll take a stab at it.  I take it you are
interested mainly in being able to send lines and highlight output, and
not so much the LaTeX session integration of EMaxima?
