Hi Barry, Thank you for some really useful pointers, I am off to do some more reading.

It seems that way. People seem to forget about the conversations and work around 2000 - 2002. We not only had RTBH (static), multi AS RTBH, Source based RTBH (why uRPF Loose check was created), BGP Community based packet filtering (QPPB - source or destination), Backscatter Traceback (Chris and Brian's cool technique), Customer triggered RTBH (another Chris and Brian trick), BGP Shunts (originally created for the Great Firewall), MAPS's grow (which had multi-AS eBGP multihops BGP RTBHs back in 1997 for anti-SPAM filtering), and then all the BGP Flow-Spec work. We even have a RFC - 3882 Configuring BGP to Block Denial-of-Service Attacks. by D. Turk. published in September 2004. This is a good conversation for NANOG, but we really need to build up some FAQ so we don't keep going over the same things every year.
