[K12OSN] Permissions for students and teachers

It seems my experience is in danger of being
completely misunderstood, so please permit me to try
once more to state my point:

I needed --and now have-- a system that requires
_zero_ maintenance of permissions/groups/ACLs after
the system was launched, so it's irrelevant whether
such maintenance would be easy or hard because it's
not done at all. 

The way I set up a working system within the
constraint of requiring zero maintenance of
permissions after launch was with Posix ACLs (in fact
I don't know how to do it another way, and I even
suspect that just vanilla *nix permissions are
insufficient for detailed student/teacher file storage
within this constraint).

If you don't have the requirement/constraint of zero
maintenance of permissions after launch, my experience
probably doesn't apply to your situation. 

thanks!
