Other possible solutions:

Use flash ram cards and a journaling file system. (soft updates may work
but you need to talk to someone that knows about them much better than I
do.)

Use a live cd for everything read only, and use a remote machine for
everything that needs write access.

Hard disks really need to be powered down instead of having their power
yanked. you are asking for a hard crash if you pull power from a drive
that is actively reading or writing.

Having this as regular part of the drives duty is asking for trouble.
