It's been a while, but the MAC address in the packets that your
server gets would be the MAC address of the next device upstream,
since that information is reconstructed by every router and other
routing type device.

Now, your MUD client could grab the MAC address and send it as part
of the login sequence.  I can change my MAC address (assuming it
doesn't break my service provider (and even if it does I can defeat
that)), but it's just another way to shut off another few percent of
the die hard griefers.
