Let the hive mind of Engadget get that for you.
"What is the best wireless surround sound speaker solution? I have a home theater where running wires is just not feasible. I have my own speakers, so I don't want a system that has speakers with integrated wireless. I've done a far amount of research and have only come across a few companies that even offer a reasonable solution: KEF, Kenwood and Rocketfish. Is there anything else out there? What do you recommend? Thank you!"
Yeah, in the future I could see a Tivo like player that had a list of movies you were interested in and knew your favorite genres and downloaded in advance and asked if you wanted to watch that movie.
The content would be locked/encrypted in the box and would just delete it if you weren't interested, but if you were, it had already downloaded it in the background/past when the content was available so you didn't have to watch it streamed and could see a full 1080P movie.
You'd have to have some major HD space to be able to store multiple possible movies the average consumer might want, but it could be done, it's just the security that would be the issue. I could see Studios unwilling to even try this based on worries that the box could be hacked and people could just being downloading without purchase every new release.
