Trouble!

I'm looking for a way to find the countries within a given range of LAT/LONG coordinates.

E.g.:

When viewing a place in Africa in Google Maps, I get out which countries that are in my current view.

This is a bit ambitious, and I think the main problem will be dealing with accuracy of the needed polygons. The accuracy of these don't need to be all that great, the borders can probably be tens of miles off, or even more.

This will be needed for the entire world.
