We found that blocking port 80 through the router was effective in getting
users to configure the proxy :-) Although we sent many emails and fielded
support questions before implementing the block. Only a few resistive
types complained "I don't like cached data", "Well what about the 5Meg
cache that Netscape keeps for you?" ... "Arr, well yes, arr."

Linux provides the transparent proxying, but it only provides about 30%
of the needed solution. It has a means of redirecting a packet, that was
intended to be forwarded, to a port on the local machine. The additional
70% is made up of a server that binds to the port and forwards HTTP
requests to the Squid cache. I have about 80% of such a server written
and it sort of does something, although when I finish it off I will
know for sure how feasable this is.

nntpcache does this. should get you
there. It was written by Julian Assange from Suburbia.
