I had an idea about the problem with rendering equations with the mathjax.
Maybe we can do some sort of hash on the content between $ $ and whatever is used for the display math, convert to html and then unhash.
This way the latex is not touched during the conversion to html.
I don't think I have the know how with editorial to do this yet, but I thought I would share the idea.
I find it amazing how little attention is given to the need of writing math. It took a while for ibooks to get it, currently no way to do it with pages on the ipad. Definitely a void.
