I agree about the term being passe ...and that it never applied to ISPs 
...and that peering is about cost reduction, reliability, and 
performance. It seems to me that many CDNs or content providers want to 
setup peering relationships and are willing to do so at a cost to them 
in order to bypass "the internet middle men". But I mention traffic 
ratios because some folks in this discussion seem to be using it as 
justification for not peering. But hey, why peer at little or no cost if 
they can instead hold out and possibly peer at a negative cost?
