Bluetooth adapter you could have

Argent Data Systems with equal success. The Byonics MT-AIO (?) will work

may be some road block in implementing it, but I think this would be a nice

"(alternative could be to send out the sound via Bluetooth to a receiver
modified to receive it and make an interface to the mic/hear connectors of
the RTX)."

Interesting idea.
