Not directly answering your question, but here's one way to produce colored syntax:

vim has a convert-to-html (or better: convert-to-xhtml) command that can be used to generate htmlified colorized perl. Here's a shell snippet from the vim docs that with a little love could be a lot of help.

   for f in *.[ch]; do gvim -f +"syn on" +"run! syntax/2html.vim" +"wq" +"q" $f; done

This is pretty slow, so I don't know how happy the site maintainers would be happy about it. Plus, it's going to be a mess figuring out color schemes for this :)
