I could be wrong but I don't think you would need more than the one set of phone wires. It says it won't affect phone service so it probably uses a modulated frequency higher than the the telephone service uses, which isn't much. It sounds like it might be using something like (or actually) the home networking standard.

I am very interested in this kind of product (over and above the empeg car

The Rio receiver isn't even close to the empeg for features, portability, etc. But since you are on empeg number 2 you probably already know that!
