I think I have mentioned this before, but we have been doing some work 
in the area of rendering HTML/XML source with bidi text. Please see
http://www.sw.it.aoyama.ac.jp/2008/pub/IUC32-bidi/ and the links from 
there. (it still has quite a few problems, mostly related to editing Web 
pages and JavaScript,...)

It also looks like we might get around to work on transposing our 
solutions to Emacs this year. It's too early to promise anything, but 
we'll try our best. And we will certainly be glad to get help and advice 
from this list.

The problem of properly (or let's say decently or reasonably) displaying 
(e.g. C) source code with bidi characters is in my estimation quite a 
bit simpler than the problem for HTML or XML. So we might do it for 
HTML/XML first and then cut down the solution to programming languages, 
or the other way round.
