This presumes that customers want the lowest price regardless of
delay. Not true. And in any case, operating a network with queues mostly
full (which increases utilization) a lot of the time is great strategy if
you want to maximize profit when you are being paid by the byte (or by the
portal access rate).
Most applications benefit from low queueing delay, so this isn't about QoS
differentiations. Only FTPs with no human in the loop want capacity with
no delay constraint.
