This is a good point to raise, to make sure VR2 and Leo stays as good general purpose tools, that are useful widely.
For the MathJax option, I think the .js and font downloading and internet connection don't happen when docutils renders a page without any math included. I've looked at the exported html file for a node without math and I can't find any js or MathJax references, so I don't think this slows down the render in any way. I think for anyone who genuinely uses math, the math.css rendering is almost useless and certainly wouldn't be regarded as production quality (unless I'm doing something very wrong). One of the reasons that I wrote VR2 was to have output that looked production quality "out of the box" and math for me was a key element. Strangely, in my mind, if I got stuck with the latex output because I don't have an internet connection, I'd prefer that to the math.css rendering (so that, in theory, you can actually figure out what it should have looked like). The IPython Notebook also uses MathJax even when used entirely within the same machine. So my vote would be to keep MathJax as the default. It seems that it won't make any difference to those who don't use math. Thoughts?
