But md5 sums change entirely upon any modification to a file.  If a
file were moved and slightly altered, inode tracking could find the
similarities but MD5 sums couldn't.  Then again MD5 sums could find
duplicated files...  Hmm...

I think the vast majority of file systems support inodes.

rdiff-backup only works on directories.  (Of course you could put that
file in a directory.)  If you need to deal with single files only,
check out the rdiff executable, which comes with librsync.
