This is more or less a basic capability present in most cards that
we should be able to make use of, however. I started looking at
changes to ifconfig to add the capability to set the MAC address
for an interface, but dropped it due to lack of time.

One good reason for having multiple MAC addresses on an interface
is to do failover: ideally you want to be able to configure your
interface to use the other machine's MAC address as well as IP
address when you detect that the other machine is down. Unfortunately,
I have no idea how one would make sure one's using the correct
outgoing MAC address based on the outgoing IP address...
