Dunno if you are already happy with this subject, but I've used DansGuardian 
for a number of prominent school districts in California with very good 
success. It's cheap, highly reliable, and a single, reasonably well-equiped 
P4 can *easily* run as a proxy for hundreds or thousands of students! (CentOS 
4, 1 GB RAM, 100 GB HDD, random P4 or Athlon processor) 

I've always bought the CHEAPEST computer possible at the local "big-box 
retailer" and never noticed a load average high enough to even measure 
consistently. EG: over 0.50... 

DG rox! 

At first, I had to tweak the filter rules for a few weeks until I had 
something I was happy with, but recently the defaults have become good enough 
that I wouldn't bother - just roll it out. 

Good luck!
