You need a physical token of some sort to identify the machine; either
you use the MAC address or in some cases the GUID or UUID storage (on an
intel system) or some other NVRAM token depending on the system in
question.

But the ethernet MAC address is about the only universal uniquifier 
that any system has, so you really don't have much choice.
