   Let's say each user has 500Mbps up and down.  I usually break out a
   shell interpreter like python and type things in to get them exact.
   A single user transfers 150 TB a month with 500 Mbps.
   >>> 500*1024**2 / 8 * 60 * 60 * 24 * 30 / 1024**4
   154.4952392578125
   So a million users would be a _million_ times that.  Each taking three
   hops is a pretty small factor, still beyond petabytes of transfer ...
   what error have I made?
