Does the OBJECT tag of HTML work in most browsers?  That's designed to 
allow fallback when the browser can't render content, and you want to 
provide alternate content.  You might be able to embed mathml for those 
browsers that support it, and fall back to images for those which don't. 
  Unfortunately, I've never tried to do it for real, nor would I know 
how to make it work in Quickbook even if I had  :-)  But html would be 
something like:

here's an equation:
<object data="/url/of/mathml/equation.mathml" type="text/mathml">
        <object data="/url/of/math/equation.png" type="image/png">
                There's an equation here that can't be rendered.
        </object>
</object>
