Wireless Dual Audio Transmitter and Receiver in one pack?

[Briguy90]

Is there a audio pack made by anyone who can do both Transmitting and Receiving. In other words I want to have a belt pack that can have both a wireless microphone attachment and an inear but within one single pack. Is this possible and does anyone make this?

I can't remember seeing one, they are likely to not be cheap as there needs to be a fair bit of engineering work to keep the RF sections of both happy when operating concurrently without significant intermod issues...
