We started experimenting with supporting different languages in the new maemo Greeters pilot today: http://talk.maemo.org/showthread.php?t=33968

I was amazed at not only how quickly the greeter idea caught fire, but also how fast and easy it was for languages other than English to show up in the signatures.

Now we have greeters of various nationalities pointing newcomers who speak their language to valuable resources, by means of every post they make, anywhere in the forum.

I call that a half-win. With a multilingual wiki, that picture becomes complete.
