Powerline is gaining traction as a solution for IOT, it is now part of the electric car-charging standard so your car can sync using a fast connection when plugged in.

"Devices are expensive because the design and certification costs for mains-voltage equipment are significant"
So is wifi certification and thats the point,
*the existing microcontroller in the appliance has already gone mains and whatever else certification
*the imp has gone through the wifi certification
You just leave each device to its speciality and interconnect them using a spare port on appliance microcontroller, if you worried about the imp touching the electrics you just use an "opto-isolator" for the interconnect which is a very old and proven technology.
The problem with hue, zigbee, z-wave et all is the cost of that gateway, the cheapest half-decent z-wave gateway for example is 130 quid, which is a 100 more than the cost of one of thier basic devices!
That'd be okay if it was one protocol to rule them all but they are all doing their own thing.
At least with the imp no niche gateway is required.
