So once you wire in the AHRS, then the data out from it automagically gets's
into the datastream along with the weather and traffic info?

I poked around in the Raspbian image they provided, and figured out more
or less how they do it. I'm not that inclined to try doing any programming in
there but it seems straightforward. I'm still not quite sure how they get
the output from the /usr/bin/stratux script, which is using 'screen' out
port 4000 udp, but I guess it's just enough to know it does it.

I also understand they haven't figured out how to shut it down yet,
other than just hope the filesystem survives the power cycling, or are they just
bringing it up readonly?

****ed at Amazon, they shipped two day prime, but elected to use USPS
for final delivery, which means my two day Prime is more likely four day ...
So other than looking at source code, and poking in the Raspbian image
I can't play with it yet. Grr....
