The current SOCKET plugin reuses the established
TCP/IP-socket (from your client) to push back the messages
from the server. This feature
is nice to tunnel messages back through firewalls.

I have once started a variant of the SOCKET plugin
which establishes a listener on client side (similar
to XMLRPC and CORBA) but i have not finished it
as i did not see any need for it.

You can however force the client side of hostname/port
(instead of the choosen by your OS), this is useful
if you client computer is multihomed (for example
has more than one Ethernet card).

You don't want to register a callback with SOCKET,
i don't think this is currently possible.
Please choose XMLRPC or CORBA instead.
