For the final word on this subject look at the National Electrical Code,
articles 725 and 800. Your local library should have a current copy. Then
check with your local building department for any local amendments. This
stuff is a matter of law. In some states (i.e. CA) you are required by law
to disclose to a home buyer any known improvements that were not done "to
code".

You could probably make a good case that the central power cabling would
be *safer* than a bunch of wall warts, but convincing an inspector or
insurance agent would be something else again.
