I thought about this but what's to stop a kid from just copying it
him/herself without chmoding it. Also,  shouldn't your chmod be 750
since you don't want others to be able to read and thus copy it out of
Dropbox_directory?
And what about /temp where everyone has read/write access?

The reason I am being so anal about the security is because I give my
classes programming tests and I don't want them being able to copy
anothers solution. After having a chat with a friend about this,  I
think the best solution may be to simply ask the kids to save their
solution as their username.py in their own home dir. Then I write a
script that I run as root at the end of class to collect the
solutions.
Concerning /temp: will anything bad happen if I temporarily (during
the exam) disable writing or reading to /temp?
