May I remind a few people here that this is a mini market research thread to help me to determine how much I can spend on building each of my devices, NOT a "let's figure out what the invention is" thread. Thanks. You're welcome to start yet another "effective occupancy sensing" thread if you so wish.

Motion sensors are the budget choice for this type of problem -- very cheap but annoying and inconvenient. I used to use motions for occupancy sensing but got sick and tired of always having to reactivate the motion sensor manually. It just made things even less convenient than not using any automation at all.
There are many uses to knowing how many people are in a room. One example I can think of off the top of my head would be when you are having a shower and your girlfriend walks in to brush her teeth or vice versa. How do the lights and music behave? How long do you need to wait for your system to realize that there is no one there and more importantly, if that time is low, how often does it shut the lights off while you're doing something that doesn't require enough movement to trigger the motion sensor?
Lastly, do you absolutely require a PC running all the time to figure out what to do when there is motion detected?
One of my goals in creating this solution is to eliminate most if not all of the headaches associated with stitching together some half-assed "occupancy sensing system", while making it affordable. While it may not be for everyone, there are a lot of other cool and convenient things that are not for everyone also. I know many people that scoff at the idea of having a smartphone, but I would never want to go back to a regular mobile phone again. That's just me.
I can put to rest any notions that I may reverse engineer a Kinect and try to sell it as my own product. Somehow I think that in a legal battle against Micro$oft, I may not fair so well. But hey, if you want to (and can afford the time and money) to hack them for your purposes and then set up a 360 with a Kinect hooked up to it in each room, then by all means, go for it. More power to you.
You mean impossible like flying machines?I don't see value in knowing how many people are in a room. And with pets and kids, 99% is simply impossible anyway.

As for identifying who's who in a room, Kinect can do this, at least on the 360 - I don't know if the PrimeSense APIs have any built in middleware for doing the same thing.
