I think you are doing this backwards. If you use the normal RH/fedora
scheme where every user has a unique group, all you have to do is add
the appropriate teacher(s) to each student's group. Then the dropbox
directory can be wx by all with the sticky bit set and only the teacher
and the student who owns it will have access to the file contents.
Or make it real simple and have the script email it.
