MAC addresses are easily spoofable, so even were this possible, it'd be
quite questionable as a security measure. Much better is to hand out
certificates with unique CNs -- OpenVPN already has the functionality to
hand out IP addresses based on CN, and they can't be faked. (Stolen, yes;
faked, no).
