At least one peer in a given PeerGroup must be a rendezvous. However, rendezvous peers can dynamically join or leave the PeerGroup. <p/>When a peers becomes a rendezvous, it publishes a special advertisement, a <code>RdvAdvertisement</code> that can be found by other peers which are looking for a rendezvous in the PeerGroup.<P><P><DL><DT><B>See Also:</B><DD><A HREF="../../../net/jxta/rendezvous/RendezVousManager.html" title="interface in
