Please do take a look at the Wookee parser module that Tarquin pointed to. It uses a syntax very similar to Wikipedia's. http://wiki.beyondunreal.com/wiki/Wookee
IT was written to replace UseModWiki's built-in parser. So I think the syntax is identical. (We've improved stuff like nested lists... minor difference)
Because it's OO, it's fairly easy to add new syntax rules.
