As I see it breaking things down should be like this:
do some google searches for: gettext bidi  
Read up on issues and how people are doing it.

Then we have two things we need to deal with:
	truncating strings
	justifcation

For truncating strings, look at: 
source/blender/blenfont/intern/blf_font.c  (function blf_font_draw)
	notice the len property, you'll need to rewrite this
	and other functions so if bidi then
	grab the string starting from the other end...

The justifcation is probably a little more complex but same sort of deal...
