hi greg...don't know if you have time to check out the latest movie trailers, but there are a couple of interesting sci-fi movies on the horizon that seem to touch on ieas expressed in your books - Surrogates (with Bruce Willis) which deals with "a high-tech surrogate phenomenon that allows people to purchase unflawed robotic versions of themselves - fit, good looking remotely controlled machines that ultimately assume their life roles - enabling people to experience life vicariously from the comfort and safety of their own homes." - and Inception (directed by Christopher Nolan) which is "A contemporary sci-fi actioner set within the architecture of the mind."
No idea whether Hollywood with give these ideas the treatment they may deserve....but one can hope...!
