There is the model where all partcipants peer through agency of 3rd 
party. That tends to be looked on as an extremely bad idea, but some 
regulatory environments encourage or enforce that sort of behavior 
particularly around the monopoly PTT.

you'll find that the details vary between entities. some bi-lateral 
relationships are going to require peering in more than one location, 
require a minimum ammount of redundancy etc. depends on how business 
critical the relationship is, how much traffic is being exchanged, the 
sized of the networks involved etc.
