I dunno, a few very strategically placed validating resolvers could subject
a huge amount of DNS traffic to a much higher bar were the senders so
inclined to sign their zones. But I tend to view these kinds of things much
more from an "epidemiology" point of view: you don't have to have 100%
eradication to control an epidemic. Same thing pretty much goes with 
internet
based attacks, IMO: when the barrier is set sufficiently high in one area,
attackers don't spend their entire time trying to break that barrier, 
they find the
next lowest barrier and move on.
