Unfortunately, the new Italian law forces us to take seriously into account
this catastrophic scenario and another one that is almost as worring: an
unfaithful SysAdmin that copies your data and sells them to KGB. So, database
encryption (and not disk encryption) is the _only_ answer.

This is the point.

The server should listen to the (encrypted/digitally signed) "Heartbeat" of a
password server through the net to prevent this kind of attack.
