(Since stalled out due issues with mapping ntp data types to postgres and postgis data types) There are some excellent caida and network geography maps that do something like this, and it would make the point, thoroughly See, for example: http://www.mail-archive.com/bloat@lists.bufferbloat.net/msg00050.html And the graphic at the middle left down (linked from the above) at: http://personalpages.manchester.ac.uk/staff/m.dodge/cybergeography//atlas/g= eographic.html Several other ideas in the above worth thinking about. I mentally see a map of the US pulsating like a old winamp graphic eq plugin, with vertical 3D bars over each location extending into space while the earth rotates under the terminator.... > > cheers, > gja > > _______________________________________________ > Bloat mailing list > Bloat@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/bloat --=20 Dave Taht http://nex-6.taht.net
