I have published my latest Backtrack 4 how-to.
Backtrack 4 - Bootable USB Thumb Drive with "Full" Disk Encryption
This is a step-by-step guide showing how to create a encrypted bootable Backtrack 4 USB thumb drive. I put quotes around full in the title because technically the whole disk isn't encrypted.
We use LVM and the native encryption routines included in Ubuntu 8.10 to encrypt all partitions except for a small boot partition that never contains any data.
This how-to is a departure from the persistent install method I have documented in the past. It also means we don't have to mess with Truecrypt or do the home directory shennanigins we were going through. I will be incorporating it into the main how-to in the near future.
As always, I am interested in your thoughts and feedback.

You shared a great solution here. Personally I’m a big fan of getting the final product – Sandisk’s encrypted USB drives do the job pretty well.
Thanks Haley. I agree that using an encrypted USB drive to start with is a good idea. However,
A) don’t have one to test with and
B) this allows anyone to use a commodity drive and still protect their data.
