The most difficult part of the implementation is probably the captcha itself.
If LiveJournal have done it, surely MediaWiki can?
Yes, infact LJs captcha code is available... as well as a lot of other captcha code. We'd only need to do integration work.
I would be strongly opposed to requiring captchas for all logins, even those which do not come from open proxies, because a visual captcha would exclude blind people from accessing Wikipedia.
LiveJournal's captcha includes the option to take an audio test.
We could also invoke the captchas against users who are editing too quickly as a way to suppress highspeed vandalism. It would be disadvantageous to just implement aggressive rate limiting, but kicking people over a threshold to a captcha every once in a while (perhaps also based on their approximate edit count) would be good.
