Yes, you're right. However, it might be a bit more dangerous to use a multicast
address... if the host you've poisoned sends large amounts of data to the
poisoned address, because you would create interupt load on all members of
the used multicast group.

This said: you needn't convince me anymore, I've tested ==A== on Ethernet
(Sparc LX, Pentium) and am just about to do the same at home with ARCnet.
