I have to admit that I have no idea how BT charges ISPs for wholesale ADSL. If there is indeed some kind of metered charging then Internet video will be a big problem for the business model.
They vary, it depends on what pricing model has been selected. http://tinyurl.com/yjgsum has BT Central pipe pricing. Note those are prices, not telephone numbers. ;-) If you convert into per-megabit charges - at least an order of magnitude greater than the cost of transit, and at least a couple of orders of magnitude more than peering/partial transit. p2p is no panacea to get around these charges; in the worst case p2p traffic will just transit your central pipe twice, which means the situation is worse with p2p not better. For a smaller UK ISP, I do not know if there is a credible wholesale LLU alternative to BT. Note this information is of course completely UK-centric. A more regionalised model (21CN?!) would change the situation. Will
