disconnect your cable modem, then try to get your google yahoo or aol mail. Still think they are decoupled? Hardly. Without a transport layer 1-3 you cant get layers 4-7 very successfully. You can get the first 3 layers from telcos cable companies wifimax as well as SAT mixed with a pots and 56k modem.
Net neutrality means you cant get thru to 911 via your voip phone because the neighbor is downloading GBs of porn and the QOS for voip cant be used by law. Your loss.
