Math.    ^_^;

1GB of volume over the course of a month is 3kb/sec sustained
throughput over the month.  (1000000000*8/(86400*30))

$5 per 3kbit/sec means that 155mbit link would cost...$251,100/month.
(155000000/((1000000000*8)/(86400*30))*5)

We call that "Time Domain Multiplexing-based profits".

Comparing volumetric pricing with rate-based pricing
is one of the best ways of tucking in *lots* of room for
profit.    :)
