[aprssig] APRS RF-ID

As is almost always the case with RFID applications, it's easy to know 
when someone/thing arrives at a location.  The bigger (and harder to 
answer) question is when did that someone/thing LEAVE a location?  Is 
it/him/her still there 5 hours later?  10 hours?  Imagine the stack at 
the EOC if you look at the last known coordinates of emergency personnel 
one week after an all-hands meeting...

All we need is to ask them to send us a file or signal, and then we can convert that to APRS and send it out the EOC APRS radio and see who is there.  Done!
