Where is NickC when you need him... this sounds like something out of his
layer4 nap idea...

Seriously, do we really need SMTP peering agreements?  I don't know of too
many places that are UUCPing their email... SMTP traffic already crosses
(BGP) peering agreement controlled links. If putting contractional
obligations there fails to work why should we believe some new and less
understood system would be any more effective?
