What's the relationship of an install DVD as is being talked about and having an image of a 'golden server' and burning the image onto a machine? It would be really cool if some localapps were already set up along with iTALC and Sabayon and maybe even CmapTools, squid/squidguard and LDAP! Could there be some kind of a hybrid--having an install DVD which burns on a 'golden server' along with some install steps which allow for a certain range of customization? These are just some thoughts from a person who donated 100+ hours of his summer (with other people's help!) to create a working thin client server.
