In my opinion, the hot setup is a small box (cigarette package size) that
clips to the back of your seat, your belt loop, or your shirt pocket and
your CURRENT HEADSET plugs into that box. Two main advantages: One, it
uses your expensive current headset in any format you desire AND if the
"wireless module" goes TU, you take the headset plugs out of the module,
break the wiretie cord, plug them into the aircraft jacks and you are back
in business. While connected to the module, you can coil the headset cable
up and tie it with rubber bands or thread that can be easily broken in the
aforementioned TU mode of operation.

That sounds like in intelligent solution.

I suppose there'll have to be another little box to plug into the
headset jacks. The audio portion seems relatively straightforward,
but have you designed a robust method of keying the mic _only_ when
intended, that won't be affected by stray transmissions?

I have just gotten my response from TI as to their recommendations for the
technology and their recommendation is to go straight ISM and not fool
around with Bluetooth or Zigbee...this from their senior applications
engineer.

It's hard to argue with Motorola, but it would seem that with so many
cell phones supporting BlueTooth now, the additional ability to
communicate with the phone might be a plus.
