With ntfs-3g you can have standard Posix ownership and protections.
A simple way to do that is to use the mount option "permissions"
instead of forcing uid and gid.

You can even define a per-user SID to record the permissions with
the same parameters as you would get if the ntfs device were
plugged into the user Windows workstation.

Having individual protections imply having different accounts, of course.
