You could always write a Java applet. If the applet used something
like a progress bar, the server-side program could notify the applet
when to increase the progress bar percentage. Another way to do it,
would be for the applet to poll the server every few seconds by having
it make a http connection to a 'quick-running' cgi that would tell the
applet the status. Based on this result, the progress bar would (or
would not) be updated.
You may also be able to write the applet in Jython, too.
Good luck...let everyone know how you decide to implement your
