Hi Patrick,

It appears you are looking for a datapipe. Here is one I found in
google:

http://www.bovine.net/~jlawson/coding/datapipe/datapipe.c

Quoting form the above url:
<QUOTE>

* Datapipe - Create a listen socket to pipe connections to another
* machine/port. 'localport' accepts connections on the machine running
* datapipe, which will connect to 'remoteport' on 'remotehost'.
* It will fork itself into the background on non-Windows machines.

</QUOTE>

See if this is any good for you, or search for another datapipe program.

HTH
