Comcast is fundamentally different in a second way: they have huge incentives to make on-demand video over the Internet unbearable, as a way of holding on to their cable revenue.<p>And there&#x27;s ample evidence of them refusing to interconnect with the backbones that provide a lot of the video traffic. The problem is not in running more fibers or more wavelengths, the problem is connecting ports in a meet-up room.<p>Comcast doesn&#x27;t really care that much about decreasing the bandwidth, they care about keeping their customers on their cable service.
