We've been working with Microsoft Research to use their machine translation technology to translate the WLK help docs into different languages.  Today I'm looking through my referrals and I found this URL.  Actually, I'm not sure what language that is, but check out http://translate.google.com/.  I can put in any English word or phrase and have it translated or I can put in a URL and have the whole web site translated.  Cool!  Of course, I have no idea how good the translation is, if you read one of these languages let me know.
