I'm just wondering whether the STIX fonts, when finally released,
would answer these questions partly (being Unicode math fonts if I
understood correctly). But yes, you'd basically have to rewrite plain
TeX (and probably LaTeX as well), whose treatment of maths is very
deeply tied to the idiosyncratic encodings of the Computer modern 7-
bit math fonts. Or did the Omega people dealt with this in some
clever way already?
As for STIX, some (postponed) target dates are finally available at
<http://www.stixfonts.org/>: beta March 2006, general release May 2006.
