You can add one line to iptables to log every outgoing TCP connect at the sync 
level, and then just browse the list in the log. Knowing you are doing this will 
help him learn about anonymous redirection networks, proxies, etc. It is 
unlikely that you will keep him in check unless you simply block everything 
except "pure" content.

If you block the BBC don't let him read the papers either, they report on sex 
and senseless violence.
