  The "unique" key is:

	(src ip/port, dst ip/port, RADIUS code / id)

  If there's no existing match, it's a new packet, and it can be processed.

  If there is an existing match, then:

	if (old vector == new vector)
		packet is DUP
		if cached reply
			send it again
		else if proxied
			re-transmit proxied packet
		else
			ignore dup
			
	else
		packet is new
		if old packet is done
			process new
		else
			WTF?

  Nothing could be simpler.  :)
