@yurnidiot This is actually how Hutchinson Telecom broke BT's de-facto monopoly on phone service in the UK in 1983—they bought the rights to use the disused pneumatic power pipes under the Square Mile in London, then trained ferrets to drag cable between sites. This let them sell non-BT leased line service to City trading desks, and was the first crack in British Telecom's post-privatization national monopoly.
