[CoLoCo] "advanced" encryption?

[Andrew]

i hope to try it someday. I am particularly interested in using a USB flash
drive, as i would rather not have to remember (a good) password, and also
having it to be able to stomp on it if necessary. That's good to know about
grub asking for a password. But, would there be a way to make a modified
grub to search for a file, and if the file is not found, then ask for a
password?
