I have played with a web base variation. It was a hack job on the
tethereal code. I would have to dust it off to see if will still
build, but you are welcome to it. It was based upon starting a
daemon that listens on a local socket and some cgi scripts that
communicate with it over the socket. I know that it could do what
you are thinking about and had considered it. I didn't get the details
worked out on how to communicate between the agent and the display unit.
I don't want to transfer the full data packets because that wouldn't
well work over a slow connection.
