I'd be interested in seeing more references on the SPAM-spoofing.  I 
assume you refer to hijacking an address space (possibly a bogon, 
possibly in use), sending spam, and switching the prefix continously. 
This is quite different than 'traditional' spoofing because above also 
requires propagation of false routing information instead of simply 
sending bogus packets.
