Too crude. MIME messages that drive the would-be attackers speakers at
the resonating frequency of human bone! Small devices that cause the
other guy's telephone to explode! send icmp unreachables for all known
networks to the crackers' machine! Abduct them and hold them prisoner
in an undersea fortress populated solely by STREAMS programmers! Make
them write line-by-line documentation for sendmail, or anything from
Athena!
