$1 per gigabyte is equivalent to $316/Mbit fairly averaged.

Yes, but:

Let's assume that someone sells at $1/gig, then is billed
$316/mb/s/mon by thier provider. Let's further assume that the
customer who is buying at $1/gig is averaging 1 mb/s, but has perfect
sine-wave bandwidth usage, ie, 0 kb/s at midnight, 1 mb/s at 6a, 2
mb/s and noon, 1 mb/s at 6p, and 0 mb/s again at midnight. (Agreeing
that a perfect sine wave of usage is mostly unlikely, but it's a
reasonable assumption that said customer won't be at the average all
month). Problem: Provider is billed for 2 mb/s.

If you can't get enough extra customers based on your better pricing,
don't lower your price (or sell it for $2/gig).
