This incorrectly presumes that being equal is necessary, when in truth
each party is going to have a threshold and method for determining the
value of the exchange that is independent of the other parties

Point in case, most networks care significantly more about what they get
out of a peering session than what the their peers get out of it.  And
this is correct and valid because only by paying attention to the actual
underlying economic reasons for making peering decisions will they be able
to ensure they stay in business.

By your reasoning all ventures should be 50/50 partnerships, which they

I'll concede if a network were to percieve themselves as a majority share
holder and think themselves large enough to effect the underlying price of
bandwidth in the market then they might focus primarily on how to prevent
another network from making more money than them from a peering agreement,
as you describe.  However, based on all the bankruptcies they should be
more focused on their own immediate operational costs and staying in
business than worrying about any single competitor.

Again, this is proof of my first point above, that each network has its
own method of evaluating peering and that their method matters more to
them than what the peer thinks.

I figured, I just couldn't let you get away with the equal remark lest
onlookers pickup bad attitudes.  :-P
