web proxy logs from school servers?

gosh no, I don't propose putting rproxy on the laptops themselves.

The way it would work is this:

 - install rproxy on the school server
 - install another rproxy on a well connected server
   (eg. rproxy.laptop.org) which might also chain to a squid or
   similar. 

The laptops would be unmodified. The school server would receive the
normal http requests from the laptops. It would add the rproxy tags
and forward to the upstream proxy. The upstream proxy will see the tags
and would get the page, then do the delta encoding and send to the
school server. The school server decodes, and sends a standard http
reply to the laptop.

The end result is lower bandwidth usage over the link between the
school server and the world.

So no extra storage on the laptops and no software change on them. 

Cheers, Tridge
