There is always hope. Seriously thought, looking at http://en.wikipedia.org/wiki/Comparison_of_revision_control_software there are a lot of choices of how we could implement this. SVN/K , Mercurial and Sun Teamware all come to mind. Simply ;) merge one of those with ZFS. It _could_ be as simple (with SVN as an example) of using directory listings to produce files which were then 'diffed'. You could then view the diffs as though they were changes made to lines of source code. Just add a "tree" subroutine to allow you to grab all the diffs that referenced changes to file 'xyz' and you would have easy access to all the changes of a particular file (or directory). With the speed optimized ability added to use ZFS snapshots with the "tree subroutine" to rollback a single file (or directory) you could undo / redo your way through the filesystem. Using a LKCD (http://www.faqs.org/docs/Linux-HOWTO/Linux-Crash-HOWTO.html) you could "sit out" on the play and watch from the sidelines -- returning to the OS when you thought you were 'safe' (and if not, jumping backout). Thus, Mertol, it is possible (and could work very well).
