Please allow me to utter some doubts on the approach as a whole, although your programming skills seem to be far beyond mine:
I admit your strutcure may be very comfortable for your visitors (provided your IP-database runs correct, as Andy said). But doesn't it violate the original idea or the static nature of URIs on a very basic level? What do I see if I present your information to my english-speaking (imganary;) chinese business partners on a trip to china? Mandarin? I guess you know what I am aiming at...
And even if you don't believe this almost-50-year-old idea of URIs is still up to date, you are always very close to cloaking and duplicate content. I'd never do such a thing if I wasn't 110 per cent sure what I was doing and how google views such a structure and if I relied on income via organic serps.
How do you present the content? Using a 301-redirect? What do rfc and google recommend for such a presentation?
