You're not paying to receive traffic from the internet at a minimum designated speed? Than you aren't buying an internet service good enough to receive streaming data from netflix or other similar services. Your options are to either pay more and get decent internet service or make netflix pay for it (and charge you via their fees). That second option would destroy the internet as we have it today.
From the Internet? Yes. I pay for a certain speed (up to, but whatever), but Netflix->Comcast doesn't go through the Internet. Currently, Netflix uses some of the 8 bucks I give them to ensure my videos are in HD by entering into peering agreements with my ISP.
I'd like to not have to pay Comcast too, as they already charge Netflix.
Surely netflix also pays for traffic at their advertised rate from their ISP. What's the problem? Oh yeah, comcast et al want to be greedy.
