Of course if everybody does this, then the traffic will balance out. Seems
to be a good thing to create the incentive, no?

In fact, TRANSACTION BASED SETTLEMENTS ENCOURAGE WASTE to the point where
it should be obvious to the casual observer that anybody reasonably
informed would never suggest them. 

Then I must be unreasonably informed because I think that some form of
exchanging money to even out imbalances would give providers more choice.

The factors that are the cause of the inherent problem with transactions
based settlements are: 

1) Either party can end up paying.
2) Transactions are generated by machines.
3) Machines can generate transactions which are either positive flow or
negative flow.  (web servers vs web crawlers as two simplistic examples).

OK. So now you've convinced us that network traffic shres a number of
characteristics with electric power distribution. Yet the power companies
seem to manage quite well with settlements. I wouldn't want to slavishly
imitate their system any more than I want to slavishly imitate the long
distance telcos. But these things can be made to work.

Oh, and before anybody comes up with a simplistic (and flawed) rebuttal
such as banning the large web crawlers from settlements, there are plenty
of other legitimate automated methods of getting flows in either
direction. 

They aren't legitimate if the sole purpose of the method is to create
traffic; that would be fraud. A webcrawler would be fine if it was for a
search engine but not if you just ran it and discarded the data.
