Any idea if X Server (either 10.2 or 10.3) can be used as a local Software Update server? I’d like to be able to have my OS X clients pull down and install updates from our server – after they’ve been vetted and approved, rather than clogging our Internet connection and installing as-yet untested updates. This seems like an obvious need but I’ve yet to find it addressed anywhere so my apologies if the answer to this is already well-known.
