The patch does exactly what I hoped for: Allows one to set an option to get LaTeX math passed verbatim into HTML for jsMath to process, while keeping the use of the ^:t TeX:t options. I've tested it on various documents. I noticed the following behavior: A comment line starting with "#" immediately before a \begin{equation} environment is passed verbatim as well. I don't think it counts as a bug, since there should probably be a blank line before \begin anyway. I can now scrap the workaround I thought up last weekend, which involved a preprocessing hook to put = signs or #+BEGIN_EXAMPLE blocks around anything found by org-latex-regexps, and a postprocessing hook to get rid of 
 tags in the HTML output. It worked, if inelegantly, but I 
think it makes better sense to have the LaTeX:verbatim option built in.

Thanks!

I'll see about updating the Worg page -- but I'm a Git novice and will 
be on a 56K modem for a bit, so it won't happen immediately.

Yours,
Christian
