The Debian 'popularity-contest' package has an interesting use for atime. It runs weekly (if you install it, of course -- nobody *has* to do this!) and determines when each of your installed packages was last referenced -- then mails this anonymously to a drop box somewhere. The Higher Purpose here is to determine what the "most useful" Debian packages are. These go on the first volume of the Debian CD set, to make a one-volume Debian CD as useful as possible.
The Windows 2000 install subsystem seems to collect similar data. Heaven only knows whether *that* data ever makes it back to its owners....
