On a DEC-10 I used in college a few years ago, it had a
system where if a file access bombed out due to lack of
permission by the permission bits, a special file was
checked for special cases such as a particular user,
group, etc.  This would allow the majority of files to
be handled efficiently (assuming the current permission
field is efficient) and allow exceptions.  Also, it
could easily be added on top of UN*X as it exists now
with modifying anything that depends on inode formats.
