How about a plugin adding a preprocessor directive to render some given LaTeX and include it in the page? This could either render the LaTeX as a PNG via dvipng and include the resulting image in the page, or perhaps render via HeVeA, TeX2page, or similar. Useful for mathematics, as well as for stuff like the LaTeX version of the ikiwiki logo.
ikiwiki could also support LaTeX as a document type, again rendering to HTML.
Conversely, how about adding a plugin to support exporting to LaTeX?
I did some tests with using Markdown and a customized HTML::Latex and html2latex and it appears it will work for me now. (I hope to use ikiwiki for many to collaborate on a printed book that will be generated at least once per day in PDF format.)

Have a look at pandoc. It can make PDFs via pdflatex. --roktas
here is a first stab at a latex plugin. Examples here. Currently without image support for hevea. And the latex2html output has the wrong charset and no command line switch to change that. Dreamland.
