People prefered an even more general themes implementations and nobody really implemented it (it wouldn't be more difficult for the most part) it is just that the making sure the interface is consistentent is even harder. The good thing is that finally you can have as part of the official install procedure n. make install n+1. make site-customs (which does customize-group "site") so that sysadmins that are not Emacs users don't forget to set things like mail-host-adress etc correctly Jan [1] Basically you would have to have "reset to site setting" options. The difficulty lies in making sure the user gets the settings he wants even if the default or the site settings change. This leads to a new custom-set-values-to-site-settings thing.
