But BTW could do it for the benefit of all of its resellers.
It doesn't work like that. You have a pipe which runs all the way through BT's network to your ISP. Even if the content in question were somehow cached on a machine in your local exchange, that doesn't really help because it doesn't see your IP traffic at all. Traffic from that cache to you would go all the way out to your ISP and then back down your pipe. -- dwmw2 - Sent via the backstage.bbc.co.uk discussion group.
