        * Looks good, but list of IP addresses and ports needs to be
          hardcoded before hand. Ok for small networks, not
          large/variable networks.

        * Doesn't seem to work on ippp0 port.
        * When run on internal interface, probably tracks internal data
          as well as externel (not sure).

        * Isn't in Debian, but I think this would be easy.
        * Licensed under an ancient Emacs license (is this really valid?
          Why not the GPL?)
        * No tutorial for beginners.
        * Looks nice and sophisticated compared with the other options.
        * Australian mirror is years out of date (according to timestamp
          on files).
        * http://www2.auckland.ac.nz/net/NeTraMet/

        * "Pick up a cheap Cisco router from a failing ISP and export
          its flow statistics?"
        * All my ISDN DOV data goes through a CISCO router at the remote
          end, and I have access to it, but I don't have a clue how to
          use this flow stuff, or what is capabilities are...

        * doesn't seem to be in Debian. Its name sounds good ;-)
        * http://ipaudit.sourceforge.net/ipaudit-web/index.html
        * looks good, will try it latter.
