need to get audio to other rooms without additional wiring

["Paul" <paul@xxxxxxxxxxxxxxxxx>]

So I want to get whole house audio, or more precisely, whole condo audio.  I
can't run extra wiring in the place.   I tried a wireless speaker extender,
but reception was sketchy between opposite sides of the condo and through
walls.

In my perfect world, I'd find an inexpensive way to extend the audio vi IP,
but that's proving hard to find as well.  I found references to a HomePlug
audio extender, but can't find it for sale anywhere.

My big thing is that I want the original audio sources to be centrally
located, and just extend the audio to the other rooms.

Anyone have any suggestions?
