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!
