Hello,
If I have a latex file mystyle.tex that contains:
\newcommand{\myBigEquation}{b=23}
and then have this in my org file:
#+LATEX_HEADER: \usepackage{/path/to/mystyle}
I can use it conveniently like this:
\begin{equation}
\myBigEquation
\end{equation}
and that exports fine to pdf but not to odt. I am fairly sure it used
to work (around 7th Oct). Can anyone confirm this?

Thanks for exercising the latex-to-mathml changes. I am happy that there
is someone out there interested in and using stuff that I have spent
some efforts on.

I am using the very latest version in the git. While exporting to odt
using
1. dvipng
- I see no issues [1]
2. mathml
- You need to register your command file with -ncf argument.
For example, if I put the mystyle.tex in the same directory as
exported .org file and add the -ncf argument to the converter as
below
#+begin_src emacs-lisp
(setq org-latex-to-mathml-convert-command
"java -jar %j -ncf mystyle.tex -unicode -force -df %o %I ")
#+end_src
I see that your sample file gets exported just fine.
Side Note:
==========
1. You don't have to export the whole file to see whether the
latex-mathml conversion is sane.
You can mark - as in marking a region - the LaTeX fragment in your
org file and do a M-x org-create-math-formula. You will see something
like this echoed in you *Messages* buffer.

2. I am copy pasting the extra "stuff" that gets attached to the latex
fragment before it get "latex" ed and "dvipng"ed.
latex-to-mathml converter ignores *all* of the stuff that goes in
org-format-latex-header, org-export-latex-default-packages-alist,
org-export-latex-packages-alist, org-format-latex-header-extra
variables.
I think I should build an "ncf" file on the fly based on these
variables and pass it to the command line converter.
Since I don't know much of latex, can you or someone in the list give
me pointers on what would constitute an ncf argument as expected by
mathtoweb.
I will make the needed changes as required.

Footnotes:
[1] LaTeX novice here.
The method I used is this: Put that style file in one of the local
directories and register that directory as a root with the MikTex
package manager. Then use this directive:
\usepackage{jambu}
ps: I am on Windows using Cygwin. So getting the directory path right
with escaping - what with spaces in directories - is always a
hair-splitting experience for me.

I have narrowed the problem I am having down to newcommands that build
on other newcommands, like so ...
If I have this in my style file:
\newcommand{\pressure}{p}
\newcommand{\capillaryPressure}{\pressure_{c}}
and try to use it like this:
#+LABEL: Equation:cp
\begin{equation}
\capillaryPressure=0
\end{equation}
then I get this xml:
<?xml version="1.0" encoding="UTF-8"?>
<math xmlns="http://www.w3.org/1998/Math/MathML">
<mrow>
<mspace width="1.00em" />
\pressur
<msub>
<mi>e</mi>
<mi>c</mi>
</msub>
<mo>=</mo>
<mn>0</mn>
</mrow>
</math>
when what I expected was P_c .
Any ideas?

This can work if the style file appears twice in the mathml command:
#+begin_src emacs-lisp
(setq org-latex-to-mathml-convert-command
"java -jar %j -ncf mystyle.sty,mystyle.sty -unicode -force -df %o %I ")
#+end_src

Where from you pulled this trick. Unless it is documented somewehere you
are most likely relying on an unintentional side-effect.
After some googling, I see that there is promising solution using
plastex. The solution is documented in the below file. The customary odt
file is attached as a proof-of-concept.

#+TITLE: How to circumvent ncf limitation of MathToWeb with Plastex?

* Summary
This document outlines ways to circumvent limitations of "-ncf"
option in MathToWeb. See this [[http://lists.gnu.org/archive/html/emacs-orgmode/2011-11/msg00017.html][discussion thread]] for understanding of
the limitations.
* Settings
Leave the converter command at it's default value - which doesn't
use =-ncf= option.
#+begin_src emacs-lisp
(setq org-latex-to-mathml-convert-command
"java -jar %j -unicode -force -df %o %I ")
#+end_src
* mysttyle.tex
In the definitions below, one =newcommand= uses one another
=newcommand=. The below defintions goes in to user specified stlyes
file =mystyle.tex=.
#+begin_src tex
\newcommand{\pressure}{p}
\newcommand{\capillaryPressure}{\pressure_{c}}
#+end_src
* LaTeX Equation
The latex equation below relies on above newcommand definitions to
be available.
#+begin_src org
,#+LABEL: Equation:cp
,\begin{equation}
,\capillaryPressure=0
,\end{equation}
#+end_src
#+LABEL: Equation:cp
\begin{equation}
\capillaryPressure=0
\end{equation}
* Flatten equations with Plastex
Use [[http://wiki.lyx.org/LaTeX/ExpandNewcommands][plastex]] to flatten out the above equation.
The snippet below is a variation of script in the afore-mentioned
link and takes input from stdin and spews out flattened equation to
stdout.
Copy the below script to =fixup.py=.
#+srcname: fixup.py
#+begin_src python
#!/usr/bin/python
# _*_ coding: UTF-8 _*_
import sys
from plasTeX.TeX import TeX
doc = TeX(file=sys.stdin).parse()
# The processed document is contained in the string doc.source
# Print to file
# f = open('PlastexProcessed.tex', 'w')
sys.stdout.write(doc.source.encode('utf-8'))
# f.close()
#+end_src
* Hack Org with a defadvice
"sneak-in" custom processing in to org core by installing the advice
below.
#+begin_src emacs-lisp
(defadvice org-format-latex-as-mathml
(before my-org-format-latex-as-mathml activate)
"Prepend mystyle.tex to latex-frag.
Pass it through to \"plastex\". Use the flattened equation - which has
ZERO DEPENDENCIES on user's newcommand definitions - as input to MathToWeb."
(ad-set-arg 0 (and (ad-get-arg 0)
(with-temp-buffer
(insert-file-contents "mystyle.tex")
(goto-char (point-max))
(newline)
(insert (ad-get-arg 0))
(shell-command-on-region
(point-min) (point-max)
"./fixup.py" nil t
(get-buffer-create "*plastex-errors*"))
(buffer-string)))))
#+end_src
* Export
Export this file to ODT and see that above LaTeX equation is
satisfactorily converted to MathML by MathToWeb.
* Disabling above advice
You can disable the above advice anytime by doing this.
#+begin_src emacs-lisp
(ad-disable-advice 'org-format-latex-as-mathml 'before
'my-org-format-latex-as-mathml)
(ad-update 'org-format-latex-as-mathml)
