That reminds me, pandoc offers compilation of latex fragments inside markdown source when exporting to pdf, which is how I typeset almost all of my math.

This is of course not even close to the same thing as official support would be, but it's good to have in a pinch, so you can typeset some math without having to bust out a latex toolchain you might not have used for a long time.

PS: pandoc offers a command-line flag to set the latex engine, which means you can use XeTeX or LuaTeX for better unicode support.
