Rendering math fonts

Depends on how complicated your math is. Simple arithmetic is obviously easy. If you get into anything like calculus, though, you'll need to write a pretty powerful and complicated rendering system that places all the little bits of notation in the right spots and makes them look nice. It's not a small job, and I'm not personally aware of any "standard" approaches to solving the problem.

Since this is hypothetical, I'm going to assume that it's in MathML, in which case you can use a third-party library capable of rendering MathML. WYSIWYG editing might be a bit more tricky.

ApochPiQ: It's should be able to interpret arbitrary notation. The content is ranging from high-school to post-graduate mathematics, so it can get very messy, and should be able to.

igni ferroque: I guess a third party license can be considered. I haven't got it all in check concerning using GPL- or LGPL-licensed code in proprietary projects, but the sponsors seem to be generous. Since I'm designing this beast, I have thought primarily of MathML and secondarily LaTeX, and the former seems to be the easiest to incorporate a renderer of. I've also considered rendering from the notation language to a PDF or PostScript, and somehow create an application "widget" capable of displaying the chosen format.

Any ideas or experiences are gladly appreciated!

I have used the R mathematical programming language extensively. It has functionality for math-function representation, similar to LaTeX, and is released under the GNU licence. As it's public domain, it might be worth contacting them and seeing if them have fonts etc that you can use.
