In theory, it might be possible to create an X server that 
intercepted the calls and made an internal representation of them 
that was more accessible and navigable.  One might start Xorg 
with either the frame-buffer driver ("fbdev"), or even the 
"virtual frame-buffer server" (Xvfb) which doesn't require any 
sort of video card at all.

I don't think anybody has attempted this, but, IMHO, it's the 
best sort of place to build an accessible-GUI solution for 
Linux/BSD, as (much like JAWS) it's an interceptor of all the 
calls for drawing and rendering text on the screen.  It wouldn't 
rely on a particular toolkit (GTK or KDE), but rather would work 
with every X application that used standard text-rendering 

Just a few thoughts on the matter...
