Yep - way outside the box - and thus the title of the
thread.

The idea is that people have permissions - not files.
By people I mean users, groups, managers, applications
etc. One might even specify that there are no
permission restrictions at all. Part of the process
would be that the kernel load what code it will use
for the permission system. It might even be a little
perl script you write.

Also - you aren't even giving permission to access
files. It's permission to access name patterns. One
could apply REGEX masks to names to determine
permissions. So if you have permission to the name you
have permission to the file.

Hard links would be multiple names pointing to the
same file. Simlinks would be name aliases.
