The basic idea of FairyNet has been rattling around in my skull for a few decades. This contest just provided the impetus to bring it into the physical world. I have been evaluating embedded OSs to put the software stack on and looking for something that was as free as could be.  Like it or not the GPL/LGPL/AGPL don't fit the bill.  I want this sucker to be embedded into cars and mailboxes and lunch pails. So BSD license it is.
