Has anyone yet come up with any good metrics for route-miles a packet 
must pass through in one direction or another? 

Right now, the closest thing I have seen to that is MEDs in a BGP 
announcement, set by a provider who knows a little something about how 
his network is built. 

The problem I see is that if we base settlement on how the MEDs are set, 
an unscrupulous peer could change his MEDs to offset a portion of his 
transit or something along those lines.

Or every content provider could buy a same-sized access provider or vice 
versa, and solve the problem that way.
