One way to build a psuedo-pseudonymous mechanism to hang off of Tor that would be easy for the Wikipedians to deal with would be to have a server that lets you connect to it using Tor, log in using some authentication protocol or other, then have it generate different outgoing addresses based on your ID. So user #37 gets to initiate connections from 10.0.0.37, user #258 gets to initiate connections from 10.0.1.2, etc.
Isn't the IPv4 address space potentially too small in the intermediate run for this approach? Sounds like you'd need IPv6...
