Would be cool except - I can't think of any reason why anyone would give their empeg an external IP address but I lots of reasons NOT to use valid addresses, so we'll end up with a lot of 10.,172. or 192. addresses, which aren't resolvable to location.

I'm having a hunt about - I remember seeing something similar to Neotrace and VisualRoute on SourceForge which mapped the route on a globe and tied in ping times showing the different routes your packets took. Well cool.
