um, isn't the point of broadcasting such that you don't have to
contact the individual addresses?  my assumption was that for
NIS broadcasting you simply put some noise on the wire, and any
masters on the local network segment responded.

more to the point, i was thinking a tool like the following might be
nice:

check_nis -d domain1,domain2 -H host1    <--- check master for serving domain
check_nis -d domain1,domain2 -b [addr]   <--- same, but broadcast
check_nis -d domain1,domain2 -x          <--- same, but invert matching sense

the last is what the OP was talking about, i guess.  unfortunately my
NIS/YP/RPC-foo isn't nearly up to the challenge, at least without
a couple RTFM pointers.
