I use squid and block all port 80 traffic unless it goes through it.  
It's pretty easy to set up users and give them different rules. Great  
for blocking specific sites (my daughter is allowed to go online to  
read her math/science books, but nothing else from 6pm-8:30pm, then  
everything gets turned off at 9:30pm, etc.
