          Walk a message through the rendezvous peers of the network: only
 rendezvous peers will receive the message.

 <p/>Only a single HOP at a time is performed. Messages are always
 delivered to the destination handler on arrival. This handler
 is responsible for repropagating further, if deemed appropropriate.

 <p/>Loop and TTL control are performed automatically.

 <p/>Messages can be propagated via this method for the first time or
 can be re-propagated by re-using a message that came in via propagation.
 In the later case, the TTL and loop detection parameters CANNOT be
 re-initialized. If one wants to "re-propagate" a message with a new TTL
 and blank gateways list one must generate a completely new message.
 This limits the risk of accidental propagation storms, although they
 can always be engineered deliberately.

 <p/><b>Note</b>: The original msg is not modified and may be reused upon return.</TD>
