SQL Slammer didn't rely upon spoofed packets to propagate (and thus  
cause a collateral DDoS due to its aggressive propagation  
characteristics); if there was any spoofed Slammer traffic at all, I  
didn't see it.

This isn't an argument against BCP38, I strongly support its  
deployment - just a clarification wrt Slammer.

      Everything has been said.  But nobody listens.
