I've done this; it proved easier than I would have expected.
It works fine for me - where "works" means, it doesn't crash the
machine, and trying to ping the address (I used 126.96.36.199, completely
off-subnet for all of my interfaces) causes packets to go out on the
wire, addressed to the MAC address given.
I'll be happy to send a copy of the program to anyone who cares to ask
for one. (Ask me for darp.c, if it's been more than a day or so, as I
may forget what I called it.)
