Ok, I guess my googling wasn't in vain. 

Are people interested in this capability? I'm interested in working on this 
feature, with (hopefully) some guidance from emacs developers.

If I wanted to start work on it:

1. Where should I begin?
2. Is it even do-able in terms of complexity, or will it touch the fabled and 
    scary redisplay engine?

What do people think?

I've have some experience with C and elisp, but mostly an emacs user 
till date. Perhaps my chance to contribute back.
