Bingo! Yes SBC is currently/about to run a WDM/PONs trial in a
subdivision near San Francisco. (Mission Hills?)in conjunction with
equipment from Paceon.
One of ethernet's problems is the distance limitation.
This is a proof of concept run, unfortunately unless there is a
drastic change in telecom regulation it is unlikely this technology
will ever be deployed :( .

Yes, fiber is relatively inexpensive, but laying it is expensive
and lighting it is very expensive.
