Uhh, how exactly does one acquire the MAC address of non-local
interfaces, pray tell. Additionally, if you could discover it, what's to
stop an impersonator from discovering it and impersonating that as well?
There are cryptographic measures which address this concern, and a lot of
books which describe them. Buy one.
