Not being able to boot from USB and having no CD/DVD drive will make things "interesting". You could pull the hard drive from the Panasonic and use a second computer to write the OS to the 20GB hdd. There was a posting here about doing something similar. I don't recall what it really dealt with. It was posted this year I believe.
As I recall, the live preview is part of the enlightenment codebase that is newer than e17. Moksha is based on e17.. I do not believe you will be seeing the live preview in moksha unless someone else decides to make the effort to port the required code.
