1. It can be used with iPad 1, 2, 3. You just need an airplay compatible device, be it ATV2, computer running your itunes, or other AirPlay compatible devices.
2. iTunes module requires iTunes running on a computer because that is how you are able to see the library and pair the iRule app with iTunes.
3. Individual iTunes Module license needs to be purchased per handset in the iRule builder. This means that if you have 2 iPads with unique GUIs you will need an iTunes module purchased for each one. If, however, you have 4 iPads that use the same GUI, then you do not need 4 iTunes modules.
4. iTunes module is purchased from within the Builder at a cost of $24.99 per handset.
5. Your iTunes Library CANNOT be empty or it will crash the app.
6. iTunes module can only play back movies/videos that do not have DRM protection on them. So TV Shows and Movies purchased from iTunes will not play.
7. Current Limitation of the module is that it can only connect to one library and only one iPad can connect to the gateway at a time.
