I understand the desire, but I'm saying it wont be technically possible to 
do so in the long run. The internet will route around such "problems". If 
you start to allow port 80 traffic freely, p2p will start to look like web 
traffic. You then have to start blocking port 80 servers on your DSL 
population and get everybody else to do the same, and whammo, we're in the 
same problems we're seeing with spam, consuming large amount of man-hours.

Unfortunately, I believe so.

Also, your figures regarding who uses bw are not the same as mine. I'd say 
a lot of the time less than 10% of the users will use more than 80-90% of 
the bw.
