Hmm.  Maybe a neutral, 3rd-party agency to get dumps of tables from
major entities and which would send e-mail with suggested aggregations
to noc@theownerofeachoffendingasn.

I will make time to start running the route aggregator at routes.netaxs.com
again; we've been fighting a random-src-address-SYN-attacker for the last
week or two.  I may have some comments on THAT for NANOG re: inter-provider
cooperation shortly.
