I assert that the lions share of this sort of traffic generation
(asymettric path where source IP is being fudged) comes from sites
where they or their service provider is aware that this sort of
thing is taking place. Sattelite/dialup, wierd traffic engineering,
Given this assumption, arranging with providers to make special
exceptions around reverse-path filters does not seem to be an
unreasonable onus to levy on either the site or its service provider.
Really, if I am producing a film where we plan to blow up a car, I'd
be required to involve the local fire department at the least. Why
should emitting _possibly_ evil IP traffic be different?
