Why should content providers be at all interested in driving v6 usage?
Only if there are people on V6 that can't get to our V4 services,
otherwise we're just doing it for the good of the net
They are interested in meeting demand, innovating, collecting
ad revenue, etc. The ROI to the given content provider is what?
There ARE more important things to spend one's limited resources on.
But we could trade putting content on V6 for them if they make their
network do multicast for us.
