[Zope] Wiki apps other than ZWiki 0.6.1

I've been happily adding ManagedMode functionality to ZWiki 0.6.1 but wonder what other Wiki-on/in-Zope technologies there are that I should consider working with. I'm looking for cataloging, graphics upload, differencing, rename and delete and don't really want to have to work on them myself if these have been done or are soon to be done. Searching on 'Wiki' appears to be useless, since the word crops up in so many contexts, hence my appeal for information. Thank you, Geoff Gardiner
