The packet's "From" address in an object packet, IIRC, should be a  
valid callsign of the sending station.  That lets other stations know  
who sent the object.

The packet's object name would be the serial number.

So every object packet could include both.  It would also let one  
sending station have 200 RFID cards if needed.
