Hi Drew,

Maybe I've missed something here, but does implementing traffic shaping on content that is sitting in a local cache seem a little bit silly...? And is it really fair to count data that is merely being pushed from inside their own network towards people's (rather insignificant) usage caps?
Last mile delivery and exchange/cabinet backhaul links are typically highly oversubscribed. Tails can now be the most expensive part of running an ISP (aside from support, if one happens to offer something resembling support.) Witness Probe-era DSLAMs backhauled by E1. (Can we say Conklin?) If you don't shape everything, including content in local cache, you won't have much of a service left. -JB
