Cool app. And a cool tool!

The Community GEO IP Project is a cool web-based app. Given an IP address, it maps it to a country/region - a highly useful thing for targeted applications! And an add-on tool for mozilla/firefox/descendents makes it immediately usable for individuals as well!

A snapshot of the moz-plugin is included.

My partner compensated for this, by depending more on things other than luck! :)

Anyways, here's some starter ... A small check-list.
