I've been using the FileBrowser App recently and have discovered that I can play songs directly from my iPad via FileBrowser, but having them streamed from my PC and then passed through to the AirportExpress Audio port which connects to my AVR. Thus, I am streaming in two directions simultaneously. First from my PC to the iPad via the Airport Express and then from the iPad to back to the Airport Express. The iPad is thus in effect a receiver and transmitter and apart from buffering the song, does not store it. Now, what I'm leading up to is this. I would love to use the iPad's iPod application to select songs with, rather than the list way/view of the FileBrowser. Currently, I have my complete library on the iPad, taking up around 15GB. It would be nice not to have the songs stored on the iPad, but still use the iPod's interface. I now know it can be done - simultaneous streaming to and from the Airport Express . Does anyone know of a way of achieving this?
