Surely the incumbent doesn't impose a cost on the bandwidth along the local loop - the bottleneck (and cost per gigabyte) is the backhaul from their locally operated DSLAM to the ISP's own network.

Yes, and it's £1,758,693 ($3.5m) PA for a 622Mbit BT Central, (so in bandwidth terms, equates to $471/Mbit per month - if the central is maxxed out). (Using $2=£1)
