Wow, it sounds like you folks are at the other end of the spectrum
compared with Seattle. I've got 3 different suppliers competing
for my connection $$.

This was what I thought about a year ago, but I thought it might
have improved since then.

I think you could handle this by periodic "pinging" and
maintaining who you are able to connect to.

There are a host of people doing the long distance fiber
stuff and there are a lot of lines drawn all over the
streets of Seattle and holes in the ground where they
are laying fiber, esp. downtown (where as you point out
you get the business $$). [Its kind of funny walking
across the street reading the blue line labeled MCI,
the red line labeled Sprint, etc.] I'm primarily thinking
of a startup that is or would do this. (As you point out
there are companies doing some related stuff. I think
Ricochet is the name of one. I was looking for perhaps some
more detail on how these companies are currently doing.)
My point would be that if the TelCo's don't get involved
with this at some point there may not be any more use
for the TelCo's. You know its "evolve" or perish if
the environment changes.

The backups are built into the protocols and the redundancy
of the datapaths. What is missing at this point are "fast"
ways of detecting outages and routing around them.
