I don't follow you.  Do you mean everybody will use the Ethernet
specific keyword (MAC or EHA?) only, and "experience problems" after
migrating his/her network infrastructure to FDDI?  Don't you think the
same would happen with homebrewn throwaway conversion functions?  And
I think Ethernet is what people use most; if somebody doesn't, s/he
starts with the general CHADDR macro anyway.  Am I talking rubbish?

(I truly appreciate that you care to enter this discussion, even though
you're not in favor of its basis.)
