By longitudinal diff, are they referring to repeated diffs à la `git log -p`? Then it isn't really different from repeating a diff algorithm on adjacent snapshots. Better tools to diff tree-like structures is still good news. Specifically for conffiles, there's already Augeas (http://augeas.net/ http://augeas.net/), a good, practical tool to map many Unix/Linux formats to trees of text.
