Everything you've said so far points to using a mounted encrypted
drive to store the db. Windows and Linux both support this, and I'm
sure Mac does too. The fact that a different tool is needed for each
OS might be an issue. It's dirt simple to setup an encrypted drive on
linux where the user types in the passphrase on each boot. Some
laptops have wonky behaviour bringing up drives on USB at bootup tho
(I'm looking at a Dell that's sitting in the cube next to me that has
issues a BIOS update can't fix.)
