Has anyone considered applying a HashCash type solution to this?
The tokens are generated by the user, and ephemeral, so the problems
associated with distributing "trusted authority" tokens and monitoring their
use without compromising the tor network are eliminated.
Users could be authenticated via server side script, adjusted on a per
session, per edit, and/or token size basis as necessary.
The drawback of course is the disparity in costs incurred by users of
differing hardware. Faster users would find it easier to use the service than
slower ones, but the mere fact that a token must be generated to access
Wikipedia anonymously at all might be enough to discourage most of the abuse.
An equitably small token might be that "not perfect" barrier you guys were
chatting about. ;)
By the way, Jimbo, it's refreshing to see an administrator of an abused
service take the time to at least discuss a workable solution. Not being a
Wiki user I have no clue what so ever about your specific situation, but I'm
all too familiar with the effects of anonymous abusers and the rather anal
screw-them-all attitude a lot of admins adopt as their own "solutions".
Whether it gets worked out or not, thanks for stopping by. :)

The problem I see with this is that as the name implies, it's
pseudo-anonymous. Tor is an anonymous network by design. And there is a
difference. It's real time nature also compounds any additional partitioning
problems a hard-keyed pseudonym setup brings with it.
Although, this too might fall under that "good enough" umbrella as long as the
tor network were disjoined from the nym creation and key distribution process
as much as possible. The nyms would have to be managed outside a tor egress
point to maintain user's anonymity. I also question whether or not a system
can be devised that makes nym creation expensive enough to thwart nefarious
users from simply collection a lot of nyms. :(
That's just my opinion, take it for what it's worth... not much. <g>
