Well, no. You want to set up a PN, nothing virtual about it.

Fine. An alarm pair is what's needed. I have met a couple folks
in Vt. who have this between their houses - one house has access
to a wireless network, the other is over the hill and can't...
Being enterprising, they identified a pair that was not in use,
found the punchdown and tagged it as an alarm pair. Been there
for a while.
Hardly on the up and up, I wait until the phone co just runs
220VAX through it to see which houses explode. But N.E. Telephone
(and most) are filled with low-motivation techs who just don't
care and understand that "doing it right" is sometimes impossible.
The CO is pretty damn far away, but there are local punchdowns
(wire concentrators - it's a non-intelligent breakout area, the
bottom of the hill has all the wires (and extras) going to the houses
and then the wires going to the CO).

As well as adding everything that's above the WIRE.

if you do have line of sight, then a pair of $40 Yagi antennae can do it.
My neighborhood is setup with a parabolic carrying 802.11a running
~6-8 miles from a flagpole to a site with a T3.
Line of sight is easy.
