Sounddude: One thing to keep in mind, there is a date far in the future which ISP's can unbundle the Fibre network by putting their GPON kit into the exchanges, very much like what has happened in the ADSL/VDSL world.
If that actually happens is another story, but its currently in the deal with LFC's.
It's not that far in the future in terms of the planning and investment/build required to do it.
