> or set up your local network to force traffic through squid (so you don't need to configure anything on the individual hosts). I know of a bunch of people who've used squid + wccp specifically to make softwareupdate not have to re-download large updates multiple times over a somewhat-slow link.
Yes, I considered squid myself already a few times. Looks like I have to investigate that eventually.
