Those are all fair points you made jparker, but in my defence i was just giving an example of how somebody who may want to seem "l33t" could fool a software firewall (say, blackice defender) into thinking that the scan was originating from somewhere else. Its my opinion that something as complicated as disabling a host in order to use its ip for your own nefarious reasons is well beyond the scope of this thread.

I'll speak to you IRC style soon.
