Ah.  You're right; I was thinking about error handling because that's
the code I happened to be working with this morning.  I was looking at
the error handling code, as well, so when I said it was impossible I
may have been wrong also.  [The ICMP6_ECHO_REQUEST handling in
icmp6_input() doesn't do any special handling for multicast at all, so
I don't see why it doesn't Just Work.]

Sorry for not paying enough attention to the question.
