Hi Alan,

nice, you might can start easily asking him to solve the installer
problem and provide an package for a ELPA repository. That alone would
allow much more people to use it.
I think the main problem for org-mode would be the fact that
org-mode->PDF is a two step approach. Org-mode exports converts the
org-mode syntax into a TeX file which then gets compiled into PDF by a
LaTeX system. To preserve the cursor position, the org-mode exporter
would have to add the necessary code already within the Tex-file.
That means whatever whizzytex.el is doing to the final latex code,
parts of it would need to move to org-mode export for PDF.
After that, I believe one could use whizzytex as it is.
However, I guess the author Didier Rémy can forsee already very
clearly what kind of feature would be needed in the org-mode exporter
to make it working with whizzytex.
Since we have now a modular exporting system, we could have a
ox-whizzytex which mainly base on ox-latex and only adds the
additional requirements for whizzytex. this requirements as far as I
can see would be:
1. Cursor position
2. Automatic definition of an export region (in the same way,
Whizzytex works on a subset of the TeX-buffer to allow fast
3. Create a function outside the exporter which calls ox-whizzytex
exporter for each change in the org-file.

Point 2 would be necessary within org-export to avoid long processing
times of org-export on large documents.

All in all, it would require to implement the functions defined in
whizzytex.el to org-mode resp. the org-exporter.

Alternatively, one could make whizzytex aware of org-mode and calling
the org-exporter for an region first before processing the generated
TeX file.

This would lead to the decision whether to have a
org-mode exporter for whizzytex
or to make
whizzytex aware of org-mode

All the best
