To complete the procedure I'd add just one thing: incremental upgrades Sending all your client the entire software package again just because your graphic designer moved something two pixels to the left is not advised. Build the mechanism to handle individual file updates.

incremental upgrades Of course -- I was concentrating on security-related aspects, since that's what he seemed interested in. Build the mechanism to handle individual file updates. Even better, distribute binary patches instead of downloading complete files -- this can often save 98% of the bandwidth. My "bsdiff" utility (http://www.daemonology.net/bsdiff/ http://www.daemonology.net/bsdiff/) is one of the standard tools for this purpose and is used by FreeBSD, OS X, FireFox, Sophos, and many others.

    It's distributed under a two-clause BSD license -- so it's basically "do whatever you like, just don't sue me".
