I have a friend that is a missionary. He uses Christian software in his ministry. So, to help him out I worked on and assembled an operating system that boots from a flash drive. I used all free stuff. I can make identical usb's from an image. So, far I am only able to do this on 8gb drives. More learning on that is needed. I used: 1. Knoppix 7.2.0 2. Xiphos 3. Bibletime 4. e-sword Xiphos, Bibletime, and E-sword are bible readers and research tools. Xiphos and Bibletime are native for linux and e-sword is Windows. E-sword I got running in Playonlinux. I also make some bookmarks on the browser for Bible research tools. All of it works great!
