Al Viro actually came up with a beautiful mechanism for it: present the filesystem's metadata as a filesystem itself. Blocks within a particular inode can then be viewed with cat, and suggested replacements can be made via echo. Such a best could be called ext2metafs and work cooperatively with the existing filesystem code. It's quite an elegant design that has utility beyond the simple case of defragmenting.
