You'll notice that most of the BTBees in those pictures use the same same BT module as the little boards we've been using, and the Bee is just a carrier board to plug into an XBee socket. And never tell anyone in public what your specific plans are, just general stuff like "Well, maybe we'll head south, or maybe east, have to see how it goes", LOL. Talk about intrusiveness, this article may be of interest! Do a google search on
"WSJ How Kid Apps Are Data Magnets". I find the direct link gets highjacked. "Big Data" knows more about you than your own govt. C'est la vie. Neuromancer in action.
