Attached is a patch to mediawiki that adds a new option $wgDontSaveIPs
What it does is allowing completely anonymous wikis by replacing the IP adress with 0.0.0.0.
(a bit background, there's a german campaign wirspeichernnicht.de, which wants to enforce a more anonymous web and provides a couple of descriptions how to disable ip saving in different apps - for mediawiki it tells to change the source, though I thought a clean option would be better: http://www.wirspeichernnicht.de/content/view/9/24/)
Attached patch is against mediawiki 1.15rc1. Would be nice if you would apply it.
I was thinking about this issue and I believe I have "the best of both worlds" solution, if someone is willing to code it. Take an IP address, concatenate it with a long string (salt), take its MD5 and use that as the anons' username. Two different IPs will have two different anon usernames, but for the readers it will not be possible to find out what is the original IP from the username.
