Did you have a chance to evaluate MathJax?http://www.mathjax.org/ I know it's come up in past math discussions and that a lot of math folks think it looks promising. A technical analysis of its feasibility on Wikimedia wikis would be great. Killing the less-used, ancient math options is great, but perhaps adding one wouldn't be too bad to do too. :-)

That's an excellent thing to bring up -- MathJAX*does* look very promising, and things seem to render pretty nicely. Need to make sure that we can either do that type of rendering cleanly with the PNG fallback (older browsers will still need the PNGs, so it may still be worth spending the time to fix baselines).

Not sure, but you might get better performance by translating the tex to mathml on the server, and having MathJax render the mathml on the client...

Size of the library, and compatibility, could be an issue for mobile but is worth checking on. (Looks like it*does* work in Android and iPhone browsers, so has a good chance of being something we could use as a progressive enhancement.)

It's actually probably a better idea to go ahead in that direction than to worry about high-resolution renderings from texvc for now. (Other image types, including icons in the UI, will still need high-resolution versions though.)
