Well, sort of.
I want to broadcast an FM radio signal playing MP3 files in a variety of
buildings from single story homes to multistoried buildings.
Small dwellings are no problems but the larger ones present a problem. The
location of the broadcast unit may be mandated by factors beyond my
control.
The power needed to reach the opposite corner might be to high.
Is there any way to use internal wiring as a short range antenna that
would
be limited to the building for all practical purposes.

In tunnels leaky feeders are used. They leak just enough signal to be picked
up at a close range.
You could try using very bad coax :-)
