I can see that file system encryption would protect you in a smash and
grab, but DM-Crypt does not protect information when the server is
running and the file system mounted. I would not rely on DM-Crypt for
HIPAA or PCI compliance. You need a solution that encrypts the data at
rest, not just unmounted or off-line. As for the lawsuits, the court
would require that you turn over the encryption keys and/or passwords so
there is no protection there.

But hey, if you can sell it to your clients, why the hell not. Billable
hours are billable hours.
