In reply to a post by MrSaffron:

Initially you need to be on a FTTC capable line, but suspect this will relax slightly in time once the demand levels for FTTPoD show it was worth doing

From a personal perspective, that would be intensely disappointing, but I guess these are the problems with commercially driven markets. I can't imagine there being much more than me wanting the service on my rural exchange given that it is actually reasonably well covered for FTTC but for certain pockets of poor coverage as a result of inappropriate network topography.
