I personally know the entire board of WikiSpot.org, a 501(c)3 nonprofit educational organization, that allows any communities to collaborate via wikis. They're generally city-focused, but something like this would probably be well within their community guidelines. And I can guarantee that the they're not going to impose censorship or advertising over there. But the software is in flux right now, and it might not be the best fit for other reasons.
And both wikis are currently running Moin Moin derivatives, which means that someone would need to write a translation script from pmwiki. (And I know regular expressions. *sigh*)
