I was not referring to any particular peering relationship, 
only problems brought about by closest-exit peering in the 
presence of highly assymetric traffic.

In the case of traffic coming coming from a peer network with wildly
asymmetric traffic, the sending network is paying to offset the traffic
assymetry; this returns the economics to that of a balanced peer or
an on-net sender (which is the normal case today).
