	IMO, you're much better off doing this at the firewall/proxy than 
anything else.  There are plenty of proxy cache servers that will do 
filtering, based on a list you give them.  Doing so allows you to 
avoid a lot of the inherent danger in setting up your own internal 
roots, especially if you are doing so for the wrong reasons.

	There are versions of squid that should do exactly this.
