Ok, so the consensus is go wired for a sure solution. This is interesting to me considering the general philosophy of wired versus wireless signals in the process plant environment. Wired is always more expensive but required for critical inputs where wireless is less expensive and easier to add to but only used for non critical data that will not affect plant operations if not available.
Rharv has a good point in that "whole home" music system is a bit silly. Yes, it is unlikely that I would every need to have music playing in every room. More likely would be living room and back porch for listening by pool.
Framing on the house will begin in January so I need to get on the stick and put my plans together and starting purchasing materials.
