   Hardware-enforced immutable (read-only) databases are a big deal in 
some environments.  Most hard drives don't have hardware write-protect 
capability anymore.  And you can't write-protect an IDE drive by just 
tying the /WR line high, because you wouldn't be able to write to the 
control registers to perform reads either.
