I can call my mail route number RFD#2 a MAC address. Also token-ring is a form of Ethernet as are all known wireless networks unless they use light. Even cable modems use Ethernet, with FDM on the cable side and baseband on the customer side. Calling SCSI MAC is absurd. All of the above, except the ethernets are forms of point-to-point communications links. IP (over/under or through) these links uses a source and destination IP and any hardware addressing scheme is incidental.
