And, data usage is highly skewed: a small group of very intensive data users tie up the network and degrade service for moderate users, who paid the same price.
Obviously, video is data intensive, but a full two-thirds of data crossing the network will be video by 2015, up from just under half of the network now.
The network will be the province of university and government researchers who access and transmit data-intensive files on the increasingly clogged, increasingly slower Internet.
