	1) What is your definition of a "duplicate packet"?  Same frame  
content?  Same IP identifier for IP packets?

	2) Display filters do not have any state - they just test various  
fields in the packet or calculated by dissectors for the packet - and  
don't count things, so a display filter couldn't do this; another  
mechanism would have to be used.
