Thanks for the suggestions. I'll have to look into it. I have limited line of sight to possible connections, and when I looked into it earlier costs were a few of times higher than the price in your link. I would also have to develop contacts as I do not have line of sight to anyone in my current circle of friends. As I said earlier, satellite meets my needs so it hasn't been an urgent pursuit. The only way the fiber connection would make sense would be if I could get others to participate. The major cable companies have decided that the customer density is not high enough to be worth servicing the area, but it might make sense if not pursued in a venue where quarterly stock performance matters.
I has been more than 40 years since I was involved in shared use of utility poles, but it was a huge issue then. Lots of lawyers involved argueing about sharing of maintenance costs, liability issues and the like. Even for companies that had long standing agreements there was always a bunch of negotiation anytime there was a new installation. It is not all stupid. How do you arrange for all parties involved to be on hand to do a pole replacement? Do you want a telephone technician moving high voltage power lines and or a high voltage lineman handling fiber optic cables?
Trenching, even micro-trenching requires right of way and going under road crossings and the like. Not cheap.
