CDNs should pay eyeball networks, too.

By "upstream" I meant "via any other path." If we're mutually willing
to talk at all, we should be willing to talk directly.

Two wrongs. It's OK for me to behave unreasonably to you because I'm
just passing it on from someone else.

I'll have to think about this one.

Fair point; I was too specific. If I'm willing to cover the -direct
costs- (such as an extra router card or man hours, extra rack space,
etc.) associated with peering with me at a location in which you have
already made the choice to peer with others I think it unreasonable of
you to refuse given that each of our respective customers has paid us
to deliver packets to the other.
Here's another one you didn't raise, but I'll throw it out there
anyway: Why should I be able to demand to peer with your entire
network at any location which happens to be convenient for me?
I shouldn't. I should be able to demand to peer with that fraction of
your network which is consistent with any other peering activity you
have at that location. If you peer at 5 geographically dispersed
locations and I only want to peer with you at one, I would think it
imminently reasonable for you to restrict the session to that portion
of your network which ordinarily transits to peers there. I wouldn't
even be offended by an offer for discount transit to the rest in
addition to the settlement free part.

I think that's disingenuous. Customers are buying "Internet" service,
not "the networks we feel like connecting you to" service. Both you
and your customer know it despite any weasel words in the contract.
