	I have a combined port forwarder/traffic dumper that would work
well.  Or, at least, I did.  I could re-create it pretty quickly I
think.  It's based on my StreamModule libraries.

	It forwards traffic back and forth and just dumps the
timestamped packets into a file.  I had a program that could parse the
file and produce ASCIIish output.

	The two 'sides' of the conversation get dumped into different
files.

Have fun (if at all possible),
