Or, let's say A finds artificial ways to send more traffic to B to balance it
out so they get charged less.  Hmmm... I don't see any way changing the charging
model addresses that.

Sure he can... He just has to change the traffic ratio.

I don't think that good content should have to succumb to advertising littering
it's pages in order to support itself.  I don't think that ftp.cs.berkeley.edu
should have to install ADs in the readme files so that you see an ad everytime
you go to download sendmail, as an example.  Get real.

No you don't, you just need something inside one of the prefixes advertised to you.
In fact, it's easier to generate what you want to a host that doesn't respond.
No need to worry about the responses counteracting your intent.  I'm not sure how
you would distinguish fraudulent traffic to enforce such a provision.  Afterall,
it could look like a port scanner, or any number of other things.

Another question that evolves is how you measure this at the MAEs.

The worst would be if this did happen.  The proposal has _WAY_ too many holes
and sounds like exactly the kind of proposal that is why we all dread regulation
so much.

Fair enough.
