I does, because the GSM chip in the phone will not give access to the
digital audio stream. It will only interface through analog I/O.

The cost given to me for this is chipset price. That is IMAO acceptable,
as we can still achieve the wanted functionality though the nice mixer
chip (if not in a completely optimal fashion).

This _does_ give us yet another reason, quite practical even, to want to
be able to modify firmware on the GSM chip as well, but that's not
happening any time soon...
