i think this can be done with a traditional file system as long as you don't insist that a file belong to exactly one directory. (that is messing with ".." is the hard way to go.) (note that plan 9 file servers already do this in a limited way since the dump file system allows an unchanging file or directory to be a member of as many /n/dump/yyyy/mmdd[.seq] heirarchies as there are dumps between changes.) - erik
