Well, they certainly should not be routing private IP ranges in and out 
their routers. On the same token then should not let a packet leave that 
claims to originate outside their IP space. I know that I don't, that was 
lesson #1 when I setup my firewall.

What is need is more MSBlasters and news coverage that beats to death the 
reason it's possible. Of course the knee jerk reaction of the industry will 
be the draconian port blocking we have so far. Worse, since it work's, that 
we be how it's done from that point forward no matter who complains it 
blocks something legit.

We're in fro a bumpy ride either way!
