As well as SPEEX, etc. I agree with this. I just wanted to make sure
we all understood it would
not be interoperable but we could use the resource. If we did this, I
suspect there would be some
pressure to offer the alternative on the ICOM equipment.

I would imagine.
The specifications from ICOM for the rest of the system are open. So
you will able to send
(say) SPEEX encoded speech (hoorah for SPEEX) along the D-Star system
but be unable
to communicate with their end users doing AMBE.
I got this directly from the Icom person promoting the D Star system
at Dayton 2004 in the
technology forum.
AMBE is proprietary, but DStars can also carry GSM encoded voice as
well as data.
