iptables can do per-user restrictions.  From man iptables, in amongst
the 'owner' module:

       --uid-owner userid
              Matches if the packet was created by a
	      process with the given effective user id.

Back to the original question: sounds like a web terminal is needed.
I've done that in the past by running just X and a browser
full-screen, with it set to restart X and the browser if someone quits
it.  No desktop environment, no window manager, no nothing.  Some web
sites can cause problems, opening new windows and other nasties, which
you can't manage because you have no window manager, but if you
control the only permitted site, that's not going to be a problem.

I think there are X-terminal HOWTOs and similar at http://www.tldp.org/
I'd love to develop one of these again, if anyone's paying... ;-)
otherwise, just take the idea and run with it.

Hope that helps,
