it's necessary but not sufficient.  but if we knew the source addresses were
authentic, then some pressure on the RIRs to make address block holders
reachable would yield entirely new echelons of accountability.

with the current anonymity of ddos sources, it's not possible to file a class
action lawsuit against suppliers of the equipment, or software, or services
which make highly damaging ddos's a fact of life for millions of potential
class members.

so please focus on "anti-spoofing"'s *necessity* and not on the fact that by
itself it won't be sufficient.  "anti-spoofing" will enable solutions which
are completely beyond consideration at this time.

(we'll know the tide has turned when BCP38 certifications for ISPs are
available from the equivilent of "big 8" ("big 2" now?) accounting firms,
and these certifications will be prerequisite to getting BGP set up.)
