Yeah, this. I suppose the closest substitute will be to configure directory listings at the http server, although I suspect UX people will get their hooks in to make it pretty instead of efficient. (Ever tried to find something specific but not currently promoted on Dell's site?)
Dell's site is a nightmare. Shopping for monitors has been one of the most inexplicably complex affairs I've ever seen. It also doesn't help that any link to their US site redirects to the dell.ca front page, making it extremely difficult to follow links from forums, google searches, etc.
Given that such downloads should be authenticated using ftp is non-ideal though, I guess.
