In the UK at least, option 1) is financially more favourable for ISPs, since the data flow is vendor -> transit -> last mile -> end user, rather than end user -> last mile -> last mile -> end user. The last mile is where all the costs are. Andy
Of course, bitstream and l2tp backhaul lend more complexity to the whole thing; the efficiency maximising behaviour for clients is exactly the opposite, as p2p traffic between local peers gets both a) tromboned up to the ISP's pop and back down again, and b) charged for per bit by BT/whoever. In fact, you want p2p content to come in from the 'net because it only transits BT's wires once... I can't think of an obvious way for a p2p client to detect this.
