Messages and topics

[Mikael]

Hi!

As I understand it topics are used on the receiving side, so if one node 
send a message, it will be sent to all nodes in that cluster no matter 
if they subscribe to a specific topic or not, so I cannot use topics to 
limit the amount of nodes a message is sent to, is that correct (to keep 
down the amount of traffic on the network)  ?

Say for example I have 10 nodes and I add a local listener on only one 
of them, messages will still be sent to all nodes, not just the one with 
the local listener.
