This doesn't seem very efficient to me.
It's hard to justify when the local phone company is probably going to roll out fiber in the next few years without a direct charge, at least for the portion on the street. Of course, that'll probably be PPPoE, maybe asymetrical, likely limited to 1G, etc. Comcast won't even quote me to come down my driveway, even though they serve my neighbor across the street from the pole at the corner of my driveway.
Of course, this assume you're comfortable with heavy machinery and can work around other utilities (most counties have a "Miss Utility" service that will mark existing services).
Or you can rent a ditch witch and do it yourself and dig by hand near anything remotely marked by the marking crew.
I'm not too worried about the overhead portion; in theory, I could group with neighbors and we all pay a share, or I could pay it and consider it a goodwill gesture to my neighbors; they wouldn't need to pay that portion if they wanted to get online (and some of them have overhead drops for electric and what not, so they'd be able to get a cheap drop for fiber, too)
