True.. At least it will have some stop in the amount of attacks.

It is quite unfortunate that it is impossible to control the 'ingress' 
point of attack flow. Whenever there is a DoS attack, the only way to 
drop it is to null route it (the method you have devised) over BGP 
peering, but that knocks the victim host off the 'net... :-(
