The end of the [UK] net as we know it: Paying for the fast lane

"Net neutrality" isn't really going to be a problem in the UK, since the incumbent (BT) is required to sell just the last mile bandwidth to other ISPs and we have a choice of many ISPs to provide the backhaul. I can simply use an ISP that doesn't mess about.

See this post from the owner of a small, highly technically clued ISP: http://revk.www.me.uk/2010/11/two-speed-internet.html

In the US, AIUI the problem is that there is a last mile monopoly in most places that includes Internet backhaul, so competition doesn't work.
