You misunderstand.  I am certainly not asking for it, in fact I  
consider it something of a tragedy that it appears the only way action  
can be taken is to take it away from technologists and give it to  
lawyers and politicians. And no, the outcome most likely won't be  
liked, just like CAN-SPAM was a sad joke.

It would seem that as ISPs implement DPI and protocol-specific traffic  
shaping, they damage the arguments that they can make claiming they  
have "common carrier" status with the inherent immunities that status  
provides.  I can hear the argument now: if an ISP can throttle  
BitTorrent (or whatever) for specific nodes, why can't they also limit  
the source addresses of packets coming from those nodes?
