Of late there's been talk of ISPs somehow "charging" media-over-IP providers (such as Google video) for access to "their" pipes. This is hard to make sense of, since when I download a video from a site, I am doing it over my pipe, which I have bought from my ISP, subject to the contract that I have with it. Google is sending the data over their pipe, which they bought to connect to the central peering points and to my ISP. However, companies like BellSouth, afraid that voice and video will be delivered to their customers in competition with their own offerings, want to do something to stop it.
To get around rules about content neutrality on the network that ILEC based ISPs are subject to, they now propose this as a QOS issue. That there will be two tiers, one fast enough for premium video, and one not fast enough.
