This is physically impossible. Think about someone using a PPP over a long distance line, or a Class C network that spans a frame relay over several states or countries. I'd block certain networks if they are a problem. The only way to screen by country would be to deny anything w/ a country's DNS name (ipfw add deny all from *.ca to block Canada, etc.) You could also refuse any hosts that do not do rerverse DNS, as many deadbeats use IP only hosts.
