I did something like it about two years ago.
I used the Squid redirect feature.

My setup was something like this:

- All clients have fixed IPs. Each classrom has his own subnet.
- I wrote a CGI-Script in perl that writes the denied IP or Netranges in 
a file
- The redirectors read this file periodically and act accordingly.
   If the client is listed in the blocking file, it's request gets 
redirected to a "access-banned-errorpage".

for a quick overwiew on this subject.

Also might have something interesting.

Unfortunately I can't send you the scripts right away, because I don't 
work there any longer. But if you are seriously interested, I can invoke 
some old connections and get it.
