If the protocol is relatively simple perhaps you can implement 
something similar to IMAP's "IDLE":

    http://www.faqs.org/ftp/rfc/rfc2177.txt

Basically the client (when having nothing important to do) 
sends the "idle" command and then listens for messages from the 
server until "idle" is canceled.

But looking into "circuits" as suggested by James seems like a 
good idea also.
