  53  *            Not currently really working, I don't like this
  54  *            call at all...
  55  *
  56  *            ...trying to make it work. I don't like it either,
  57  *            but perhaps it's worth the load it causes to net.
  58  *            This requires flooding of the whole net like NICK,
  59  *            USER, MODE, etc messages...  --msa
  60  *
  61  *            The above comments have long since irrelvant, but
