[AG-TECH] tell rat to read audio from a pipe

That is likely to be difficult; rat has some fairly deep assumptions within
that the device it's getting samples from is a full-duplex audio device.
However, I think there might be some code in there that handles the binding
of two half-duplex devices to make a single full-duplex one, though I've
not used it.
You might also consider not using rat to send that audio; rather, write an
app using the libcommon RTP library to send the audio packets out directly.
You'd have to package them up with an appropriate encoding (linear 16bit is
easy) and with the right packet type.
