what areas are prioritised by BT?

I'd put money on them prioritising areas already well served by Virgin - I'm very happy with my Virgin Cable TV, Phone, 20MB b/band. (Granny's watching streamed foreign TV, Kid is playing multi-user games, Wife is Video Skyping, I'm doing some PHP/mysql online development work).

BT would love to turn up in "Virgin territory" and offer cheaper fibre on the back of Govt. subsidy - but I'd not move, I've had the dubious pleasure of doing business with BT before, never again. Virgin do suffer from a help desk staffed with morons but name any big provider of any "service" that doesn't have that problem.

As regards "unlimited broadband" frankly I'd prefer honest metering or capping to the otherwise inevitable "tragedy of the commons", there will always be some greedy buggers crying foul if they can't spend 24 hours a day maxing out the line capacity downloading pirate movies, why shouldn't they pay per GByte?
