Hi James, The need for just such a box has been discussed at the Hamvention, and we also dreamed up the microphone form factor. It would need a patch cable or jumper system to interface with the various mic/spkr and PTT standards.
Inside we would need some sort of 32 bit processor, but perhaps not a full Linux machine. It would make (open source) Digital Voice available on any legacy HF SSB or VHF FM radio without a PC, and be completely open and hackable. Major work between where are today and that is a fixed point port of Codec 2. I've got some thoughts on how I can delegate that work more effectively, e.g. automated unit tests that will show pass/fail on any modified code.
