We have (4) model homes next door to each other that we would like to have the same source of music playing from one house to the other. Our plan is to have (2) speakers on each porch so that when customers are walking through, the music will be seamless. Each house will have its own WiFi and unique IP address. It is possible for us to run a CAT6 from one house to the other to feed off the same IP if that is nessicary.
