I'm not sure what you mean by "latexy". The two things that would be needed are 1) you can enter equations in latex syntax or something similarly convenient, 2) tex-quality rendering. MathML guarantees neither, and I really doubt OO can do either (or anything even in the same ballpark), but I'd be happy to be proved wrong.
I do have a little script for converting a file full of latex equations into PNGs that I use when using Impress. It works okay. But I'm not really fond of Impress for all sorts of other reasons too.

I think he's referring to OpenOffice's equation editor, which uses MathML as it's internal representation. It meets both of your criteria: A somewhat LaTeXy syntax and ok looking formulae.
