I would like to suggest that with the next firmware update, the Linux kernel inside the WD Mybook Live should include the non-hardware related modules such as encryption and loopback device modules which are available by default on normal Linux systems.
My goal is to encrypt the /DataVolume volume using the built-in Linux 2.6 full disk encryption and provide a way to unlock the volume once after boot. For me personally, a SSH login would suffice (using libpam-mount), but for most people, providing a way via e.g. WD Quick View would of course be more user friendly.
This way, all data is readable after unlocking it once, but becomes inaccessible once the device loses power (and has to be unlocked again). The Linux 2.6 crypto API provides ways to unlock using multiple passwords, so each user could (theoretically) use his own password to unlock the drive.
I have exactly this set up running in a G4 Mac Mini running Ubuntu, which was my former backup server, but this machine is limited to 250G of storage, and I would LOVE to see WD NAS disk encryption get enabled, with the low power usage it has it would be my definite future backup disk!
