Why did not you use the example "Bird and Alligator"? They have different sizes, but their meeting do not cause _the protein exchange_. -:) Seems there is 2 different cases (in ISP example): (1) big ISP and small ISP working in the same market and on the same territory; (2) Big ISP in USA and other ISP in ZIMBAMVE. If Alligator meet the hear, it try to eat this _piece of protein_. If he'll meet a small bird - we would see the example of mutual cooperation. Why not? (may be I have to name it Crocodile? I am not shure). Really there is 2 theard in this discussion - (1) and (2).
Its like two animals meeting in the jungle at night:
If you are of equal "size" you'll quite happily sit about, exchange pleasantries, and even peer IP packets with zero dollar settlement.
But if either creature is bigger than the other then you can expect a somewhat different outcome, normally involving a forced exchange of protein.
