My view on this is...I'd like a movie in the same "world" as Blade Runner. Different characters...different storyline. (I'm working on a story at the moment to add to my website, which could be "interrpreted" as a sequel. (More on that as it comes to a close.)
My other thought is...it would be great (IMHO) to have a production of DADoES...absolutely true to the book. It would be a MULTI-VOLUME release...such as what "Lord of the Rings" did on their dvd release. I've got some actors in my mind, whom I see performing some of the parts, when I read the book (In my minds' eye.).
Those are my thoughts on this.
