The problem I was thinking of occurs with inline
greek and other math symbols. Their vertical alignment is
inconsistent. They hop all over the place (I assume because
the bottom of the image is alligned instead of the baseline
of the characters). I will try the patches.

Standard numbering in a math document designed primarily as
hypertext may not be what I would want... And you are right,
automatic generation of references across multiple documents
could be quite tricky, unless the original document is a
(La)TeX paper, in which case a conversion program like
latex2html makes sense.
