I've just tripped over a tool we're using here, called Interman. It uses
the Ethernet interface on the local machine to watch all the network traffic.
Unfortunately it is only available in pre-compiled form I've seen
SunOS, Solaris2, decultrix, decalpha and sgi available on ftp-sites) and it
won't monitor serial line access.

You might talk them into releasing the source code for doing a port. (The
source code is available at some cost).
