Hrmm, I can't tell by looking at a traceroute who paid whom, if  
anyone.  Care to explain your magic?  Is there a code in the in- 
addrs?  Perhaps "sl-$FOO" means something in Sprint-speak?

Secondly, does anyone really give a rat's ass who is "SFI" any  
longer?  There are at least 2 fully "SFI" networks who can't route  
half as well as a whole slew of non-SFI networks these days.

Anyone who thinks "X pays Y" is more important than any of the  
metrics above needs to reevaluate their priorities.  (At least from a  
customer / engineering PoV.  I wouldn't suggest $NETWORK's bean  
counters have the same priorities as their network engineers &  
customers. :)

IMHO, of course.
