This is already coded, see subterfugue.org. It has even nice
gui.

These are rules for "normal" untrusted application:

# Generic configuration



# It is okay to read/write to any file, if user confirms that.
path ask read /
path ask write /

# Any world-readable files are okay, too
path allow_if_public read /

path allow write /dev/tty
path allow write /dev/null
path allow write /dev/zero

# We do not want to be asked about bash...
path deny write $HOME/.bash_history

# We do not want to receive warnings about bash accessing $MAIL
path deny read $MAIL

# It is okay to connect anywhere, if you ask, first
net ask connect *
# It is okay to talk over unix domain sockets
net allow connect Unix*

path allow write /tmp/delme
