It would allow Wikimedia to distance itself from knowing people's identities, but still allow admins to revoke permissions if people acted up. The user shows a real identity, gets a token, and exchanges that token over tor for an account. If the user abuses the site, Wikimedia site admins can blacklist the user without ever being able to learn who they were or what other edits they did. More: https://cs.uwaterloo.ca/~iang/ Ian Golberg's, Nick Hopper's, and Apu Kapadia's groups are all working on Nymble or its derivatives. It's not ready for production yet, I bet, but if someone wanted a Big Project....
I think nymble is superceded by blacr, http://freehaven.net/anonbib/cache/blacr-ndss.pdf. It's model usecase is Tor-using editors wishing to work with Wikipedia.
