[CoLoCo] Ubuntu Encryption Question

[Andrew]

i was also interested in that as well. I think it would be neat to have some
sort of key on a usb drive, and have the system automatically search for the
key and unencrypt the drive if the usb is available. But, i dont know what
kind of work would need to be done for that.
