I have (3) surround sound receivers in 3 different parts of the house and I would like to have whole house music. If I had an ATV at each home theatre location and I was able to stream to all (3) simulataneously then I would have a simple solution to whole house music. I believe the only workaround is to use iTunes to possibly do this, but what about using some other app like pandora, spotify, amazon music, etc? If apple allow streaming simultaneously they would sell a ton to people who want whole house music with different zones on a budget. Let me know if there is any simple solution to my problem of wanting to use (3) different receivers around the house to power different sets of speakers simultaneously.
