I think you are missing the twist, this isn't a broker like IBM Websphere,
etc, the 29West node is a passive participant in the communication.  Clients
send and receive to servers without either party connecting to or explicitly
addressing the "network log" device.

Think of it like a monitor port on a switch, so for example you can see all
the TCP streams go through, extract out the SMTP messages and then have a
archive of all incoming and outgoing email.
