Beware though: the [no-math] option may have some side effects. The
redefinitions it eliminates, namely:

\DeclareMathSymbol{0}{\mathalpha}{legacymaths}{`0}
\DeclareMathSymbol{1}{\mathalpha}{legacymaths}{`1}
\DeclareMathSymbol{2}{\mathalpha}{legacymaths}{`2}
\DeclareMathSymbol{3}{\mathalpha}{legacymaths}{`3}
\DeclareMathSymbol{4}{\mathalpha}{legacymaths}{`4}
\DeclareMathSymbol{5}{\mathalpha}{legacymaths}{`5}
\DeclareMathSymbol{6}{\mathalpha}{legacymaths}{`6}
\DeclareMathSymbol{7}{\mathalpha}{legacymaths}{`7}
\DeclareMathSymbol{8}{\mathalpha}{legacymaths}{`8}
\DeclareMathSymbol{9}{\mathalpha}{legacymaths}{`9}
\DeclareMathSymbol{\Gamma}{\mathalpha}{legacymaths}{0}
\DeclareMathSymbol{\Delta}{\mathalpha}{legacymaths}{1}
\DeclareMathSymbol{\Theta}{\mathalpha}{legacymaths}{2}
\DeclareMathSymbol{\Lambda}{\mathalpha}{legacymaths}{3}
\DeclareMathSymbol{\Xi}{\mathalpha}{legacymaths}{4}
\DeclareMathSymbol{\Pi}{\mathalpha}{legacymaths}{5}
\DeclareMathSymbol{\Sigma}{\mathalpha}{legacymaths}{6}
\DeclareMathSymbol{\Upsilon}{\mathalpha}{legacymaths}{7}
\DeclareMathSymbol{\Phi}{\mathalpha}{legacymaths}{8}
\DeclareMathSymbol{\Psi}{\mathalpha}{legacymaths}{9}
\DeclareMathSymbol{\Omega}{\mathalpha}{legacymaths}{10}
\DeclareMathSymbol{+}{\mathbin}{legacymaths}{43}
\DeclareMathSymbol{=}{\mathrel}{legacymaths}{61}
\DeclareMathDelimiter{(}{\mathopen} {legacymaths}{40}
{largesymbols}{0}
\DeclareMathDelimiter{)}{\mathclose}{legacymaths}{41}
{largesymbols}{1}
\DeclareMathDelimiter{[}{\mathopen} {legacymaths}{91}
{largesymbols}{2}
\DeclareMathDelimiter{]}{\mathclose}{legacymaths}{93}
{largesymbols}{3}
\DeclareMathDelimiter{/}{\mathord}{legacymaths}{47}
{largesymbols}{14}
\DeclareMathSymbol{\mathdollar}{\mathord}{legacymaths}{36}

were done because LaTeX expects to find some characters in maths at
specific code points, corresponding to the position of these
characters in the Computer Modern math fonts. Common TrueType or
OpenType fonts are likely to have the same characters at different
positions, which may yield unexpected results, such as a "(" in input
not producing a "(" in output, and requires that you redefine
yourself these characters to correspond to the appropriate code points.

I don't know where the situation stands right now. I seem to remember
Will was working on a new package, doing for math fonts what fontspec
does for text fonts. The problem, though, as I remember it, was that
this was sort of unsolvable until a decent Unicode math fonts
existed, and I think Will was waiting for the STIX fonts to come out
before finishing and releasing the package.

At least that's what I remember vaguely, it haven't looked at the
problem for a long time. It seems the package is what's now called
unicode-math, with a link from Will's page <http://
