I tend to agree with Jon.  Intercepting the file-opening calls is
going to wreak havoc on all utilities not linked with the hashing file
opens if the opens are always intercepted.  Eg, heaven help you if the
hash function happened to pass "STDIN" to DOS!  I'm pretty sure STDIN
and the like will have to be special-cased in both directions to be
really bullet-proof.  On the other hand, intercepting the calls only
for automatically generated, read, and deleted (ie, temp) files is
going to require exactly the kind of surgery on GCC that has already
been discussed by Alan Eldridge among others.
    To be efficient, transparent, and not break your system, the
solution would have to be implemented within DOS.  Microsoft isn't
going to do this!  Anyway, your floppies won't be binary compatible
with other DOS systems....  And if you're gonna un-DOS DOS that
drastically, why not go all the way to a new OS (OS/2. NT, Un*x, ...)?
