ICMP is only one of a dozen ways to attack people. There is no point
in specially targetting ICMP.

Unfortunately, it is, in practice, impossible to log ALL the traffic
across a very busy router at an exchange point.

In my opinion, the only long term solution here is software that is
"smart" about tracebacks -- that is, can be directed in real time to
log certain classes of traffic.
