I'm not sure that's really the point. BT for example will sell a 17Mbps service,
To whom? I'm pretty sure they sell no such thing. They will sell an up to <some value> which incompasses 17Mb/s as a possibility for some people
The problem for BT is that the costs are the same regardless of the connection speed (and do note what Mr Saffron says as well). If BT only charge by connection speed it will end up doing one of two things:
* Overcharging customers on 'short lines'.
* Losing money on customers on long lines.
Given the costs involved in 'shortening' lines BT will likely just refuse to supply a service beyond a certain line length so you'll get nothing.
And it really is the ongoing bandwidth demands that drive costs. That's why leased lines are so much more expensive per month. The 1:1 contention means that you get to see the true cost of data transportation. Heck - even looking at a business grade DSL connection shows a price jump due to the lower contention/higher priority.
