Network end users to pull down 2 gigabytes a day, continuously?

You are correct. Today, IP multicast is limited to a few small closed  
networks. If we ever migrate to IPv6, this would instantly change.  
One of my previous assertions was the possibility of streaming video  
as the major motivator of IPv6 migration. Without it, video streaming  
to a large market, outside of multicasting in a closed network, is  
not scalable, and therefore, not feasible. Unicast streaming is a  
short-term bandwidth-hogging solution without a future at high take  
rates.
