# This is an example of a Ruby Lemma that publishes message and *also* uses the
# "Guest" model of connection. This Lemma will advertise that it's available on
# the local network, without a specified room, and will only begin speaking
# messages once a server requests a connection from the Lemma.

# wait for a message from a server that may want to connect to it.

  # the socket has closed. The connection would have to be restarted.
