So this only matters if the video stream can actually be delivered to your house with reasonably good bandwidth. I hope there isn't someone between your house and HBO's servers who has an interest in degrading that traffic!
THIS. I predict the next big peering standoff to be between HBO and Verizon / Comcast based on these news. Looking at my HBO GO connection now, HBO seems to be getting bandwidth through Level3. I expect to see the same "congestion" shenanigans from the cable companies that we saw during the Netflix peering dustup.
