Robert, it's been done. To some degree that's nullfs (if nullfs had been working; the VFS is broken). I've written stackable f/s templates exactly for the purpose of developers using them to build other f/s w/o having the many hassles of writing a full f/s. My wrapper templates, called wrapfs, work on freebsd, linux, and solaris. You can build all kinds of f/s using them, including f/s that do not require persistent storage. See http://www.cs.columbia.edu/~ezk/research for papers, and http://www.cs.columbia.edu/~ezk/research/software for tarballs. Let me know if you have any questions. Erez Zadok.
