Independent of, and in addition to, other locking schemes, how about an active process that monitors for either high acceleration (the laptop being moved) or no

  You could use code from here on a Mac, http://osxbook.com/book/bonus/chapter10/ams2hid/ http://osxbook.com/book/bonus/chapter10/ams2hid/ It would probably be best to have multiple triggers.

  I remember writing a script at some point to lock the screensaver in case of high acceleration or if the laptop is tilting by more than a few degrees. The idea was to lock it if was snatched (or just moved around). However, that would only be effective against a petty thief and not against a forensic team. In that case you'd probable want to additionally flush the filesystems (if you care about data integrity in case of a false positive), overwrite the encryption keys in memory (maybe on disk as well, but then there's no coming back without a backup) and shut down. I wonder if the init scripts prompting for the password, cryptsetup and the LUKS subsystem have been designed to always overwrite copies of the entered password and decrypted keys ASAP.
