Get one of those fm transmitters, and use old radios in each room for music. Or carry a ghetto blaster or computer speakers and a portable player from room to room. If I need a tv in another room. I carry one in there. Not sure how good networking over electric cables is these days, but would seem like an easy alternative to wifi. Rather than run Ethernet cables through the house, I ran them on the outside of the last place I lived. It was easier, and less messy (at least from the inside).
