Would it have to a unique token? What about a simple password system that 
is filtered thru a pgp handshake?
There are few loopholes in part 97 that might give us room to come up 
with something. Example we can use spread spectrum and send telemtry and 
commands. I am assuming that to be legal any third party must be able 
toresolve the pass word. The system I am thinking of relies on a 
uniqueness of a dynamic signature.
