USPS sounds important.  One thing we consider when protecting information
on security lists is the problem of "rubberhosing" -- being physically
forced by someone else to remove the security from the information, to keep
your own life, health, or livelihood.  Hence a way is needed to protect
crucial information from deletion _even_by its_owner_.  But you've probably
heard this already.
