I need to clarify my points a little bit. I don't mean we don't need controllable devices. I need door locker, window slider for years. But I will not buy a thermostat for > $100, because the way to produce the "things" is not economic.

We can have centralized program to control all the things at home. Two usages:

1. Need to control from remote: we should control them via OS level security to reduce the unnecessary cost to speak HTTP no matter how cheap the OS is. If they can be controlled directly, why do we need them to understand HTTP?

2. Need to talk to each other: they can talk via the controlling program. They don't need to be that intelligent to talk to each other via HTTP.

By the time when we have every "thing" at home, you can see the difference. The cost must be reduced to almost nothing in order to make home automation popular with very low additional overall cost compared with the existing devices. Again, think about it, we'll have 100 things at home, are you going to buy every thing for $100? Not necessary, not scale.
