They really haven't decided on the standards yet, plus in a big
organization like ours, we have many thousands of routers and
networks that would have to be updated.

Indeed thats how it is done, but even on small networks these
updates soon take up a significant portion of the bandwidth, and
timing is always a problem.
And of course voice requires networks with QOS (quality of service)
which the current Internet does not.

Yep, we know, but in our case we have dozens of different entities
and regulators on our backs. Laying fiber is EASY, it's everything
else after that that's hard. and of course all these companies are
just doing this in downtown areas, no one is laying it out to
residential areas, except very wealthy areas.
A GOOGLE search should yield some names.

I didn't phrase this well, and you have a very good grasp of some
of the problems. SONET was specifically designed to handle the
outage/reroute problem and is the best example of this tech.
It's all in the hands of the regulators I'm afraid. If things stand
as they are I see three possible results.
1) As the issue stands the RBOC's have little, no, or even negative
incentive to deploy a fiber network. This could result in
drastically smaller RBOC's offering telephone only. Data will be
left to a hoard of others none of whom will build a network, except
in business areas.
2) If the RBOC's can offer data separate from telephone and without
the telecom act restrictions, they might build a separate data
network.
3) Some bizarre compromise of the above two.
It just pain's me to know we have something so much better planned,
and yet I sit here with my feet cast in regulatory concrete.
