And, I assume, at the Ethernet level they're *not* identical, presumably by having different source and/or destination MAC addresses.

By having a machine with multiple network interfaces on the same LAN segment and having its ARP implementation spit out different MAC addresses to different clients as a form of load balancing? :-)
Or by having the switch do other weird stuff internally? What's the switch set up to do that causes it to duplicate the packets? What is it doing to the MAC addresses?
