          Propagates a message onto as many peers on the local network
 as possible. Typically the message will go to all the peers to
 which at least one endpoint transport can address without using
 the router.

 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.

 Loop and TTL control are performed automatically.

 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.

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