Hi folks,
A few comments:
1. "raw LaTeX" is by far the most accessible format. The information 
in a source file conveys exactly what appears in visual form in the 
PDF or the DVI. Moreover, there's nothing more liberating than 
producing professional quality documents with no sight.

2. To the best of my knowledge the law in England and Wales 
stipulates that the conversion of published materials into a format 
suitable for the blind or, people with other disabilities, is 
permissible so long as the converted materials are used for academic 
or generally non-commercial purposes.

3. I should forget PDF or, worse still, DVI. PDF specially is the 
opposite of everything raw LaTeX offers the blind.

No matter how much progress is made by the developers of screen 
readers somehow PDF remains less than accessible. It's a bit like 
failed relationship in which one partner tries to win the other back 
with expensive gifts.
