Paul, none of the suggestions I have seen so far (in more than
five years) offer something which 1. is an effective solution,
2. is technologically possible, and 3. places the burden of blame
on the perpetrator.
If you can propose a solution which does not imply:
...imaginary technology to intuit a commercial message from
its content (can anyone say "content based routing"? 
...making the management of the affected resources more
rigorous than current practice
...punishing the ISP for the actions of its customers
...complex or impossible deployment issues
...added administrative cost
I and many others would LOVE to hear about it.
I am the first to agree with Shakespere on the value of certain
members of the legal profession.
This time, however, I do not see any recourse. Do you?
