Vint,

We have developed systems that live on TCP/IP networks and communicate
with each other in a symetric peer fashion.  When one of these boxes
starts up, it attempts to open TCP connections with its peers.  The
connection attempt starts actively by sending SYNs.  If the remote
end doesn't respond, the TCP port goes into LISTEN, assuming that the
other end will eventually initiate the connection.
