If we setup a wide network of trusted, distributed sensors, then we can 
setup an auto-countermeasures system. Eg blackhole routing those networks 
which originate scanning attacks which are detected at N or more sensors.

Only TCP scans with full TCP handshakes would be used, since udp can be 
spoofed. A nice sensor net of labreas geographically distributed would
make a nice countermeasures net.

Of course to be *really* effective, a number of exchange points or a large 
number of individual peers would have to subscribe into the blackhole
list.
