Paul, the most common way I've run into this is to do the following as
the superuser (and doesn't require EC2):

    mkdir -p /root/some-private-directory
    cd /root/some-private-directory
    chown root .
    chmod 700 .
    su some-non-privileged-user -c "erl blah blah blah..."

The "some-non-privileged-user" user can't read anything in the current
directory, which is still /root/some-private-directory.
