You may want to get your attorney (Lawyer) to check into the legality of publicly broadcasting music from your iPhone.
Even "Elevator Muszac" requires a license.
I am opening a bakery in a few months and would like to be able to find a speaker system that I can have multiple speakers connected wirelessly and use my iPhone to play through all of them at the same time. I don't want a surround sound system or something I have to run a bunch of wires. I am trying to find a way around running an expensive and permanent speaker system into the ceiling and sub woofers and amps and all that crazy stuff. It's really just for some music nothing crazy no bands or anything.
I can't seem to find a speaker that I can link with multiple different ones and be wireless. The best I have found is the HiddenRadio but its not available yet.
