I'd rather use designMode/Midas-like approach of having a white canvas 
(an iframe in html) to play with. contenteditable tends to be a little 
too granular for free-form editing.

It's possible, yes. Both mozilla and IE have HTTP subrequest components 
accessible from the javascript layer (actually mozilla cloned the IE 
ones, so portability is not a big issue there)

doable? digest this first

and come back to me. This is the list of algorithms that they 
implemented in SubEthaEdit.

Scary to death, if I have to be honest.

But *very* intellectually stimulating.

Count me in, but this is going to require *massive* thinking, 
expecially on how to reduce the problems of latency over the network.
