Is there a market for zone control in lighting systems? Sure. A small one. I don't think most of my clientele would be up for paying a whole lot more money for those features. But I could see where some clients would.
The dimming thing seems a little hoaky to me. First of all, I am not sure I agree with the premise that certain parts of your lighting system should be more dim at certain parts of the night. Second, if you are using LED, then your system is already extremely energy efficient. To the tune of $1-$4 a month in energy use. So dimming them for a few hours is going to do what, exactly? Trim that cost down to 50¢ to $2? Really doesn't save much. So I'm not sure what the advantage is to that. But I'm sure someone somewhere would like that feature.
