The remote app is a very small app that connects to an iTunes library on the same network. There's no storage on the iPad at all, as it's just a remote. It controls the iTunes library. Presumably then, you'd have that library somehow connected to your sound system.disappeared said:how time consuming is it going to be adding ~5000 songs to it?
There are actually many ways you can stream or control audio from your iDevice. Obviously, all the officially sanctioned methods tend to involve iTunes on a computer.
What format is your music at the moment? If it's in mp3 or aac, then iTunes already plays it, and no conversion is needed. Just import to the library.
