 If you have to have metalized plastic I guess that would eliminate the
 main attraction of gas line broadband where ever plastic is deployed

 Verizon just buried fiber down my street.

 FIOS will be available in several months.

 Fiber doesn't corrode,
 doesn't conduct electricity due to lightning,
 doesn't oxidize or otherwise deteriorate
 due to the elements although
 there is an old Phone Co. term, 'the backhoe fade'
 but that applies to anything buried.

 Given all this, who would bury a metallic cable these days
 for new communications distribution and why? It will only
 deteriorate and need replacing long before the fiber will.

 Have I missed out on a pivotal point in the discussion?

 Oh, by the way, all the gas pipes I've ever seen installed
 under the streets here in PA and DE are a sort of  pinkinsh
 colored plastic, although the distribution feeder into the
 meter in the basement is still black iron.

Fiber can be affected by water and rats I have heard. Fiber can be cut
by things other than rats and backhoes. Most companies in lower
Manhattan had redundant fiber, went out of the building in more than
one direction, but found on 9/11 that most of their redundant
connections shared the same right of ways blocks away that were all
cut by the WTC collapse.

Same problem with sewer, gas, or power lines IMO. I like wireless for
the last mile. You have more control, know where your connections are
and can fix the problem much quicker than with fiber in many cases.
Putting up that first full duplex Loea Gbps connection, one of the
first Loea did anywhere, took three hours from the time the truck hit
the curb at the first building.
