I tried to get communication (network) peoples interested to compile such
type of 'communication' maps... but soon I felt a lot of troubles to get
the right one data sets... network traffic, lines, nodes, relays, gateways etc..
The peoples from w/German research network at Berlin/Bonn where not very
cooperative when this question had been raised up... but such new map types
are in progress...
