An idea,

[Kelly Prescott]

hmm, a interesting concept...
The problem is that by the time the x server sees most of the stuff, it is 
just screen position renderings.  The server does not have a concept of 
letters, characters, etc.
The server knows where you click on a screen, for example, but it just 
sends the information to the under lying application which is responsible 
for deciding if you have clicked on a button etc.
This is a over simplified explaination, but for our purposes, it will 
do...
Bottom line is that what ever toolbox, library, wigit set, rendering app, 
or what ever, it must feed the textual information to some interface for 
the screen reader to get at it so it can be read.
Hope this helps.
