I did outline something that should (I think) deal with that aspect in 
particular in a post last month, but Eli did point out it would still 
necessitate further nontrivial changes to display code - he's got a lot 
on his plate already (understatement) -see:

My minor concern is that if the inverted hscrolling method is 
implemented and an emacs is formally released with it, then a subsequent 
implementation of rigid (including window-width-aware rigid) hscrolling 
might also have to deal with offering the inverted hscrolling behaviour 
some users have by then become accustomed to as an option.  That would 
likely be more horribly complicated than only supporting the one type of 
hscrolling.  It's premature to worry about, though, there'll presumably 
be a period with bidi code public in branch and then trunk, but not an 
emacs release.
