GeoIP or browser language to set CPG language?

[Mats]

...just an idea; why not use any of the free GeoIP-db's or the browser language to set the interface language automatically?

If at all implemented this has to be admin setable as well as a user preference - even though I am from India I would still prefer to browse in English rather than Hindi....

This is already a feature.
