I didn't imply that it did.

But the ability to block without causing significant collateral damage 
becomes more and more difficult as IPs become less tied to the 
organization using them.

That said, you're right that people are doing it now.  Consensus from 
friends running their apps on EC2 is that you can't expect to be able to 
send any email from EC2 and hope for a high deliverability rate.
