That is one possibility that may arise from an Ofcom study of the UK's existing ducting network to check its suitability for distributing fibre networks. Britain finds itself in a situation where other European countries are ahead when it comes to fibre roll out, with notable examples being Sweden and France (where three providers already offer speeds of 50-100Mbit/s). It turns out existing infrastructure in place for other utilities such as water and energy could be used to deploy fibre at a much lower cost than if roads had to be dug up. Several companies have already setup such services to offer greatly improved speeds to businesses via the sewer system. If similar programs could be setup for consumers then speeds around ten times what is generally available wouldn't seem such a big leap. Of course, as this is the UK there is plenty of red tape involved. Now I just have to hope someone will do a trial in my area.
