I think personally that "fonts" are the wrong approach for complex equations. They are essentially "graphical" objects, and need to be "drawn". SVG seems like by far the best approach.

I don't really see what you're trying to say. An SVG is still going to need a font to display the individual symbols making up the equations. (Or else recreate the symbols with a vector graphic commands, which is more or less the same thing, resource wise.) The SVG is going to allow you easily to specify the font to use and the exact location of the character, so the formatting is right. We still need the fonts.

Fonts are one issue, laying out the symbols properly is another.

I really don't think JavaScript is the right direction to go in. Let's not introduce a bunch of security holes into eBook readers if we don't have to. Native MathML or LaTeX support would be much preferable. In the meantime, SVG support is a nice compromise.

It's not 100% clear from the website, but I would expect the STIX fonts to be freely distributable. I assume they'll clarify such matters when the fonts are actually released.

Okay, now for the nitty gritty...
I see instructions for embedding fonts here: https://www.mobileread.com/forums/showthread.php?t=61587
But how would I adapt this for the beta STIX fonts? I want to double confirm that previous attempts to use MathML weren't being stuffed up due to a lack of fonts..

One can't display math reasonably w/o having fonts for the special characters involved --- using vector objects is markedly inefficient (fonts and their handling are highly optimized) and requires significantly more space.

Placing math fonts into an svg would be reasonable, so long as all svgs in a document would be able to access fonts from a central repository.
