  I've not seen anyone address the changing picture aspect
of your problem yet. A simle web page that displays a
static graphic of the network could update itself with
an HTML update command. I don't recall the format of the
command right now. The update period would hopefully be
close to what your server is getting new frames. For
instance, a server application updates a web accessable
picture once a minute. The client side would update
its view one a minute and expect to see a minor change.
You could just leave the client web page up to see
activity throughout the day.

  Java or perhaps Javascript could handle such things
on the client side. I'm pretty sure there would be
a server side implementation, but I've not written
anything like that yet.
