A very short sighted business plan concentrating on populated areas, while the likes of the urban sprawl get 40-100, and ever more providers, the country side moves in other directions, with sat broadband and 3g and testing 4g in Wales, BT your market will shrink and the new frontier of the countryside will be gone to you forever.
The Infinity product can already do 100 mb connection, however due to the last copper mile no one will get that kind of speed and the only way forward would be a total revamp of the last mile to fibre, which won't happen for a long time, if it will ever happen. If the last mile was converted over to fibre then there wouldn't be any reason not to get 1 gb connections, or up the hardware to 10 gb connections which can only be seen in the computer industry at this time.
At this time Infinity is all about demand and supply and it starts with the most populated areas, however I live in a village with 4000 houses and not all of the village has FTTC, I asked about this and found out that there is no demand for this product and the houses within that area won't be getting FTTC, yet I have it and was the first to be installed.
People are correct about the lack of good broadband services to the smaller communities, its all about greed, however this is what makes the money world go around. The only option will be wireless broadband which the goverment are trying to get roll out for 2012 where the whole of the UK should be getting at lest 2 mg connections regardless of where you live.
There is no real answer to the questions being asked other than the next package which will be 100 mb connection which we won't see until 70% plus FTTC coverage has been completed, at this time BT are on thier own with supplying this product even though other ISP's have signed up to roll out FTTC packages and dragging thier heels in getting it out there. If they stopped beating about the bush and got on with it, I am sure we will see a bigger incease on supply of FTTC.
