So then should it also support external DACs?

This will turn the whole portable world upside down if this usb kit can be used for the ipod/itouch family in addition to the Ipad.
No "Sound Preferences" in the iPad OS, that could be a snag:
"The iPad lacks any visual indicator that audio has been moved over to the USB connector, nor does it offer any controls I can find in the Settings app or elsewhere to choose whether the internal mic and speakers or a USB device is used."
And obviously it would have to run off of the battery if either the camera adapter or a LOD were employed
DAC's need a digital signal (USB, optical, etc.), and they convert that binary information into an analog signal (audio left/right, etc.), which then can be amplified into sound that you can hear with your ears. We as humans cannot decode 1's and 0's with just our brain.
Records and various audio tape formats are purely analog, and you would need the opposite, an ADC, to put the music on a computer drive or optical disk.
DAC: digital-to-analog converter
ADC: analog-to-digital converter
A Pico/Predator type of device is just an analog sound amplifier if there's no DAC, and a DAC is just that unless combined with an analog sound amplifier.
