This is a great hack/proof-of-concept but for anyone remotely concerned about the integrity of their data in the event of a theft, I can't recommend something like PGP Whole Disk Encryption (http://www.symantec.com/business/whole-disk-encryption http://www.symantec.com/business/whole-disk-encryption) enough. There are other options, including free ones on Linux, but for Mac I think this is the best implementation. With my laptop insured and my data unrecoverable the package gives me total piece of mind.
