An interesting article on thinkbroadband about FTTP on demand.

Perhaps IDNet could look into this and maybe participate in the trial as it is certainly something worth considering. I'm currently on a FTTC cabinet and would be willing to pay for a FTTC upgrade to get greater upload speeds as long as the install cost wasn't to high.
Already a thread on the subject http://www.idnetters.co.uk/forums/index.php/topic,28334.0.html
