Not yet AFAIK. pdflatex can't even make ``tagged'' pdf last I checked.

That's a tough one --- why not just provide the latex source instead?

Most screen readers for example will flatten out the Pythagorean  
Theorem to, `` `A' two plus `B' two equals `C' two''.

As an alternative, you could make a .html document where the  
equations would be bitmaps and the alt text would be the latex source  
for that equation --- Adobe does this on their opensource site.

Hopefully the above will help.
