There's an extension which implements Usenet style syntax (ie. *bold*
and _italics_) in MediaWiki -- and it's really simple.  I think that
this will at least give you an idea of how such an extension can be
hooked into MW; in fact, you could probably use the extension as a base,
cut out the Usenet formatting code, and paste in the Markdown code:

If you do it that way (which would involve a different way of hooking it
in), then you can still have MediaWiki syntax work inside the tags, by
calling the MediaWiki parser on the text.  Have a look at this:

	http://meta.wikimedia.org/wiki/TabbedData_extension

Inside the <tab> ... </tab> tags, it converts tabbed data to a table;
but at the end of hookTab(), it calls the parser, so that any remaining
MediaWiki syntax is handled.  Sounds like what you need.  Just replace
the table conversion with the Markdown stuff.

That's yet another approach... personally, I would allow my users to
write in either syntax, and keep it the way they wrote it.
