From: Sean Bellsouth provided some estimates of bandwidth costs in the
future as video on demand and high-definition video becomes more common on
the network.  "Internet" traffic is a very small part of the future
bandwidth requirements.  Voice/VOIP is completely lost in the noise.

This is a bit of a mental exercise because it assumes everything will be
unicast across the backbone.  In reality, no one is designing their networks
that way (not cable, ilec, clec, wireless, etc).

  Todays average residential broadband user consumes about 2 gigbytes of
  data per month, Kafka estimated, which costs the service provider about
  $1. As downloading feature films becomes more popular, they might
  consume an average of 9 gigabytes per month, costing carriers $4.50.

  The average IPTV user will likely consume about 224 gigabytes per month,
  he added, at a monthly cost to carriers of $112, a giant leap from the
  less than $5 attributed to Internet use. If that content were
  high-definition video, the average user would be consuming more than 1
  terabyte per month at a cost to carriers of $560 per month.
