A layer 1 architecture isn't going to be an economical option for the
foreseeable future so opining on its value is a waste of time...its
simple
not feasible now or even 5 years from now because of costs. The
optimal
open access network (with current or near future technology) is well
known.
Its called Ethernet and the methods to do triple play and open access
are
well documented not to mention already in wide spread use. Trying to
enforce a layer 1 approach would be more expensive than the attempts
to
make this work with Packet Over SONET or even ATM.

What is about a normal Ethernet deployment that you see as a negative?
What problem are you tying to solve?

Well, Scott, assuming you mean ethernet over fiber, then you've just said
that it's economically infeasible to deploy the physical layer of 
precisely the architecture you advocate.

I find these conflicting reports most conflicting.

As for "what problems are you trying to solve", I just itemized that.
