OK, I'll try it...
One more wild idea

I can understand why for every new user multilanguage'd text (with your hack) shown in one language. And probably can to have correct reason, whyby default this language is English (in my case) - it's language of user, under which httpd daemon work. But...
this difference haven't big sense for Europe, and have for all regions, where english isn't primary language. I want to suggest add one more variable "default language", in order to get by default content on default site language, not in english
