Need a wiki

[volvoguy]

My absolute favorite wiki software of all time has to be MediaWiki. It
also happens to be the software used for the Wikipedia and their whole
line of wiki sites. It's GPL'd, but alas not in Debian/Ubuntu at all.
Installation is dead simple though and uses MySQL for the backend.

It doesn't fit some of your requirements, but I thought I'd throw the
idea out there anyway. :)
