Considering the original posters updated content, I would say that this is clearly the best answer. IP::Country won't be perfect and it won't match everyone in your target countries - but it will match the ones that can be resolved back to appropriate country codes. As I had mentioned elsewhere in this thread - if the person uses an ISP that is outside of their own country or SSHes into a machine outside of their country and fires up links or lynx, there's nothing you can do about it.
