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.
