Miami Dade Emergency Services has implimented a newer system. I believe this is what crossflo is trying to do.

If you look at the link at the top of the screen for Firehouse Software, it is a software employed by %99 (my figure) of the 37,000 fire departments in the US, and %100 of the departments in CT.
There was also a Wireless Communication expo in Las Vega$

There were 355 companies exhibiting.
I did not see Crossflo represented.
Good Luck,
