Thanks for the info James!
I'm also serious about pursuing one of these systems as well. I
wonder if we can get a discount going here for multiple units. I'm
anxiously awaiting Glens (W8AK) hands on findings.

Ok guys ... here is what I found.
It is not Motorola proprietary format, but rather it is ETSI
(European Technical Standards Institute) (standard number ETSI
TS102 361-1). It is a DQPSK scheme. This is a published standard,
and I just might start pursuing its use rather than D-star at this
point.

As far as I can tell, it's a proprietary Motorola format designed for
business and industrial use.
It should be legal on the ham bands, as long as it's not encrypted, so
anyone should be able to buy a radio off the shelf, program it, and
talk.
I don't know if there is any prohibition on the emission class,
probably
not. It should fall under an FSK format.
