I just added this proposal:
http://en.wikipedia.org/wiki/Wikipedia:Village_pump_%28proposals%29#Privacy…
I assume that's the best place to discuss it, but if it's more appropriate for
this list, let me know and I can redirect.
==Executive summary==
* I've built a software package called nym which could be used to allow users
of anonymizing networks and shared-IP networks like schools to edit Wikipedia.
Privacy would be preserved, yet admins would still be able to block IPs of
vandals.
* The software includes patches to WikiMedia, which I have submitted to
MediaWiki's patch-review system.
* Wikipedia needs to decide whether to accept my proposal and patches. The
patches are small and easy to implement; mainly it's a question of whether the
admins are willing to try it out.
