This has probably been answered already but I am trying to determine the maximum number of ATV2's you stream to via Airplay from a single itunes computer asssuming you have a dedicated 300mbs wireless network just for ATV2? I want to have 7+ ATV2's throughout the house connected to TV's and be able to airplay to all ATV's from a single itunes computer...basically a whole-house audio system. I have already done this wirelessly using 3 ATV2's with no hiccups and was wondering what the limitations are?....Network Bandwidth?..ATV2 Hardware limitations etc...Does adding each additional ATV gobble significant bandwidth or is airtunes more of a one way broadcast type deal?
