MathML has some support.  MathJax might be used instead.  SVG images
work pretty well, and LaTeX code can be embedded in ALT tags.
Nevertheless, imagine a formula which takes a full line on a printed
page being forced to fit on a small e-reader. Reflow, shrink, or pan?

Experimental packages include accsupp and axessibility.  For the lwarp
package (LaTeX to HTML), I've introduced an ALT key for
\includegraphics, and the next version will introduce \ThisAltTag for
custom one-off tags. SVG math and some chemistry have the LaTeX
expression included as an ALT tag, unless it's a complicated nasty
thing in which case it can be set to a generic default.
