It's quite convenient already (see below), so what exactly would the
option involve?  Can the javascript and fonts be located remotely?
I.e. can org host them like it hosts org-info.js? (I just tried that and
failed)

I wasn't aware of mathjax but I've just had a quick play.

Some notes

- MathJax appears to be the successor of jsMath (same developer)
- Darlan Cavalcante has written a Worg article[1] on using jsMath with
  org
- Basically, to use jsMath all you need is

  #+options: latex:verbatim
  #+style: <script src="/path/to/jsMath/easy/load.js"></script>

- To convert this to MathJax, all you need to change is the path:
  /path/to/mathjax/MathJax.js
- I found that a document with lots of maths rendered visually the same
  in mathjax as jsMath
- Mathjax was considerably slower to render the maths. (I think that
  under the hood it converts to mathML which jsMath does not do (?))
- Whereas google-chrome did not work with jsMath for me, it worked fine
  with MathJax. This is nice because google-chrome produces a clean pdf
  (firefox adds the file path at the top of the document)
- We can put the latex in a src block using
  #+begin_src latex :results raw :exports results


As I said the other day[2], one reason I am excited about these
technologies is that we can produce a pdf with pretty source code
fontification via htmlize (rather than ugly[3] latex listings output)
and genuine mathematical fonts rather than ugly dvipng images. I do this
via CUPS print to file under linux, which allows the web browser to
produce a .ps or .pdf. I'd be interested to know how we can make this a
more "genuine" org export path.

[3] No one has replied to my post the other day, so I'll be more
contentious. Can anyone demonstrate how to make source code look
anywhere near as nice using listings in latex as with htmlize.el?
