Here's another article by Ian Grant on BT's broadband philosophy. Community Fibre (B4RS) can do this, where BT just can't.

he House of Lords presentation referred to in there is a couple of hours, but Dr Peter Cochrane (ex BT CTO) describes EXACTLY what B4RS is all about. We are one of those "little" companies who want to change the game.

If you can spare the time, well worth a watch/listen.
