Wordpress Locale Switching on Accept-Language Header

Question

Is there anyway to get wordpress to automatically switch locales based on the HTTP Accept-Language header?

Similar to how ASP.NET can do it with their globalization="auto" config setting. The reason for this is that I want my dates to be custom formatted based on where you are viewing the site from - not what the wordpress site settings use for everybody around the world.

This way somebody from the USA (en-US) will see 12/25/2011 but somebody from Australia (en-AU) will see 25/12/2011.
