But, it is possible to change the MAC address (see the rest of the article)

Plus, for some old NICs there was duplication of MAC addresses. If I remember correctly it was for NIC that were designed for different topologies, token ring and bus. It caused a problem when people bridged the two networks.

That said, MAC addresses should be unique if they are on the same network. (I think that unique MAC addresses is a requirement for ethernet)

Sorry to confuse you.
You are right. MAC address should be unique. What I means here is MAC address is just a part of key of concern hash table. And along with other still open parameter, MAC address would served as the key of the concern hash table.
