[mat-wg] Traceroute visualisation

Good talk by Emile on visualisation of traceroutes and the various sources of geo-loc that can be munged and derived to try and give more accurate info. While there was talk of commercial geo-loc such as Maxmind, what about mining the DNS for LOC records? Has there been any investigation of that? Or am I just an ossified dinosaur, talking about LOC records? :) Cheers, Mike
