I want to do a full install of Lubuntu 64-bit on a 32GB USB drive with full drive encryption. Is this possible? Does anyone know where I can find a tutorial/guide? I want to use this to boot any random computer into my environment.

The developers on gmane.linux.kernel.device-mapper.dm-crypt say LVM is a really bad concept so I don't want to use it.

All suggestions are appreciated.
