Netflix could load something from fast.com on each Netflix navigation right? Ultimately if they're playing cat to Netflix's mouse how much does each mitigation strategy cost them relative to Netflix? I wonder if it's more cost effective to process that much traffic through shapers than it is to increase bandwidth between peers or allow Netflix to drop their boxes within their networks.
