Your figures for the BT Central capacity are very wrong.

The price BT charge an ISP for Central capacity is about £240 per Mb/s 
hence a 2Mb line carries a potential cost to the ISP of nearly £480/month 
just for the Central capacity.

Of course ISPs don't charge on that basis as to date usage patterns have 
tended to be bursty allowing for contention to work. Currently many ISPs 
are growing more concerned at the rise in persistent usage patterns 
arising from long running p2p session and the growth in online 
distribution of large media.
