Sounds like what you are after is a Kiosk type setup. Can't help you with the remaster but can point you at a version of Puppylinux that may suit your needs and/or serve as an example for a DIY project. It's been stripped of all hard disk tools and is meant for library or lab use. It was/is called iPup and was availble from www.toddrichardson.com - a note to him on his website should net you more info. Hope this helps.
