I have DansGuardian set up on my home Linux server that acts as the 
router for our home network, and it does a great job of web filtering on 
the fly.  (I have grade school kids at home).  You basically configure a 
transparent proxy so all HTTP traffic is filtered, and it's configurable 
as to what categories you want to allow or block.  I use RPMs available 
from RPMForge.
