It is my understanding that the Xbox On-Demand streaming is just talking
to the regular On-Demand servers at the head-end (just like On-Demand
over QAM works); the traffic has nothing to do with Microsoft's network,
peering, etc.  That's why Comcast doesn't count it against any caps; it
isn't transit traffic, it is local.
