A few months ago I developed an intranet app for a team of consultants. The project manager asked if they could save it to their shared network drive. Naively I said yes of course just save a link. Later I found that he had just done "save as" from his web browser and created an offline version! It made me wonder if it is something that should be possible. Storing html files containing actual data on a drive is actually quite elegant: * The user has an intuitive understanding of files and can manage them using existing tools. * Easy to backup. * User level security is as simple as setting file permissions. * All computers have a web browser that can render the content. Could raw html be used? I am not sure that a packaging format is even necessary when you can use a data URI for images.
