are you sure? Does jsmath really implement TeX math mode? I.e., if I write a
nifty macro, and use it in math mode, will jsmath be able to handle it?

It is *very* cool.  What I like most about it, it uses TeX itself as
typesetting engine.  I.e., no matter how obscure your macro, it will be able to
handle it, since it doesn't handle it itself :-)

Moreover, it is able to produce a wide range of output: html+pictures,
html+jsmath, mathml, whatever.

I guess, however, that there is a speed penalty.  My idea of using it was to
have all the documentation written in LaTeX, transform it with tex4ht at build
time or when needed, and cache it.
