While this is true for most consumer users who work using their providers DNS, for networks such as enterprises/corporate locations, it's common to find they all share a common internal DNS resolver, which may be located in one physical location, while the clients are sprawled all about over the world. I think this does give a bit more power to the geo-aware dns services (such as Cisco GSS), if they implement it.. but it's a long way off, as many ISPs and networks would need to upgrade their resolvers to support this extension.
