  I understand where you are going.  I don't know how easy this would
  be to articulate to a non-technical, time-limited audience.
  For instance, OS/2's HPFS (and HPFS386) file systems are installable
  file systems and exhibit several properties of which you speak about UNIX.
  It gets very technical, very quickly, when you start discussing superblocks,
  fnodes, and resistance to fragmenting...as inherent in the directory and file
  structure design...not to mention Extended Attributes and b-trieve algorithms.
  [reference back issues on this subject at  www.edm2.com].
  Clearly, neither FAT nor VFAT have this level of technology.
  Unless a definitive "high-level" approach can be taken to prevent flummoxing
  the audience, it could even backfire.  I'm not sure how to show technical state-
  of-the-art at a particular time in light of justifying how MS should have done it too.
  However, in terms of HPFS, my understanding that MS does have rights to 
  [some?] parts of it when they were co-developers with IBM in the late 1980's.
  Perhaps a case could be made that, at least, they certainly knew about these things,
  and also perhaps that they advertised C2 file system security before it was true.
  (I'm not so sure it is yet true even with the latest NT).
