Actually, I've found use for sending out broadcast pings. It can be
very usefull when you are at a node in an internet that for one
reason or another seems to not hear anymore. Say you are the net
administrator and don't have a lot of time. Can anyone hear? Throw
out a broadcast ping and see what you get back. The information can
be very useful in a gross sort of way.
