Two Airplay devices and external disc drive or storage

First day of using great djay on ipad2, questions:

  1. Can you add support for two AirPlay devices: Airport Express (AE) for speakers and Bluetooth Headphone for cue (preview songs).

  2. Can cue goes to ipad heapdhone out (stereo) when battery of Bluetooth phones is low - no splitter cable please.

  3. Can I use pendrive or other device as a source of files (limited storage on ipad) - when I did it through iFile then djay crashes and ipad resets, file isn’t added to library. My ipad is jilbraked so no IOS 6 so far.
