Sheetal - re "how easy it would be for normal human I mean non engineers to connect it"
That's a very good question. There have been a variety of devices over the years that have attempted to allow non-engineers to electronically install automated controls. The X-10 system comes to mind as the most well know. They weren't Internet connected, but they used communication over power line to allow switching a variety of devices from a common panel or from a PC.
The most common type was a small box - not much bigger than an outlet. The box plugged into a wall outlet and a lamp or something would plug into the little box.
I could see something along those lines working with WiFi Internet connectivity. Whether non-engineers would be willing to try it out is a different question.
Good list. But how easy it would be for normal human I mean non engineers to connect it. Also with so many brands of electronic devices being there in common household, what is the common interface needed. What if that interface is not present in yur TV or Washing machine.
But overall its a good thing and was long awaited.

We have created a radio platform that extends the WiFi technology for many interesting possibilities.
One of the extension is frequency shifting so standard WiFi protocol can be run on any frequency band within 100 MHz to 6 GHz. This allows all the WiFi benefits to be extended to different industry verticals and their allocated frequency bands.
Another extension is to improve the range. With high power radio modules, the operating range can be 20-30 miles.
The radio platform is field proven in 100's of military and commercial projects. Here is the brief technology overview. http://doodlelabs.com/products/technology-overview.html
I hope this "commercial" post is a useful addition to the topic being discussed.
