I'd like to be able to monitor tcp/ip traffic on my system without
having to rewrite all of the socket()  related system calls to include
instrumentation. Is there an easy way to notify a process that a
connection is being made on that particular machine?  Once I have that,
I believe I can make a daemon that will transparently pass this
information between communicating processes. 

The program xmon which monitors X protocol streams, does something close
to what I want; it looks like the X server to the clients, and looks like 
the clients to the X server, but it knows what port numbers to listen to; I
don't, and therefore have to somehow monitor all ports for
communication requests.

Any input would be appreciated,
