Well, for me the math does not work at all.
Rather, the CM fonts don't work; as yet I don't know why.
It may have something to do with my teTeX file-structure,
but there's no -debug tracing in xdv2pdf so I cannot tell
where it is actually looking for the .otf fonts.

Same as tex, etex, pdftex, etc.

Sure.
I'd like to help get XeTeX fully working with LaTeX first,
then ultimately extend the math-capabilities to be able
to use Unicode code-points for greek letters and math-symbols,
the forth-coming STIX font encodings, and such-like.
These are the problems that I've encountered so far:
1. \mathcode (as above)
2. lack of tracing in xdv2pdf (mentioned above)
3. cannot create a fresh working xetex.xfmt from plain.tex
(so that it preloads .tfm file locations from my installation)
Here's what happens when I try to use such a locally \dump'd
format:
[glenlivet: XeTeX samples] rossmoor% xetex CM-test.tex
This is XeTeXk, Version 3.14159-2.1-0.3 (Web2C 7.5.2)
%&-line parsing enabled.
(./CM-test.tex [1*** malloc: vm_allocate(size=2584555520) failed (error
code=3)
*** malloc[28133]: error: Can't allocate region
fatal: memory exhausted (xmalloc of 2584553356 bytes).
[glenlivet: XeTeX samples] rossmoor% bad XDV file: DVI_PRE not found,
b=-1
4. fclose: Bad file descriptor problem. (Is this just cosmetic ?)
When \dump-ing the format in 3. this happens for
cmr5.tfm cmmi5.tfm cmbf5.tfm
(but not cmsy5.tfm or for any other design-sizes).
With LaTeX jobs it happens for some .fd files and .tfm files,
in particular whem AMS packages are loaded.
5. lack of driver-support for color
(this has been mentioned previously)
Is color part of the AAT interface ?
If so, then this shouldn't be too hard to do.
But there also needs to be color for non-AAT constructs.
6. lack of driver-support for active hyperlinks
Preview.app supports hyperlinks in Panther, but TeXshop does not.
Surely there are some APIs for this now.
7. support for scaling/rotations/clipping etc. of imported graphics.
How much of the \includegraphics from graphicx.sty
can be supported, for a xetex.def driver file ?
Given an interface via \special syntax, I can write appropriate
driver files: xetex.def (for color/graphics)
and hxetex.def (for hyperref)
Cheers,
Ross
