Serious question: What about EarthLink's non-EarthLink-owned modems?  (They 
do lease some modems, I have dialed into one before. :)  And what about 
NetZero-type companies that outsource all of their modems?

If he is measuring traffic off routers, I do not see how he could 
differentiate between traffic on modem leased by $PROVIDER_A and traffic on 
that same modem an hour later leased by $PROVIDER_B.

Also, does he, or anyone else, have any explanation why [insert favorite 
obvious big backbone] is missing from that list?  I know most of the ASes I 
used to see as "big" are not listed.
