Much live programming could be done without significant additional 
burden if the community could agree on multicast delivery standards.

With YouTube's commercial offering on top of Netflix, Hulu, etc. and 
cable IPTV we're probably pretty close to the tipping point now.

This is already the case in many markets. It may not be IP peering, but 
there have been several recent instances where a broadcast TV 
transmitter is off the air due to some kind of failure and their cable 
feed keeps on chugging. Obviously there is some form of connection 
between the TV station and the cable company that doesn't rely on OTA.
