Creates a server, monitors a tail -f output for IP addresses, GeoIPs them and sends them to a map. Run it and visit http://yourhost.com/map
Grab npm and:
npm install maptail
Tested and working with node.js v0.4.4.
maptail <file_to_tail> [host] [port]
This is based on mape's wargames.
Could not be possible without kuno's GeoIP module.
