As far as I can tell - you can't get real dsl to fiber fed home - under the
current scenario of DSLAM in the central office.  By definition, DSL runs
over copper.  The only way to get DSL to fiber fed homes is to put the DSLAM
out in the field at the consumer end of the fiber but outside of the home.
They would have to have neighborhood DSLAMs.  I am not sure this is cost
effective for most.  You need air conditioning and the like in these units.

IDSL does run over fiber now.  Northpoint and Rythms already offer this
service.
