The big story over the last three-to-four years is that much of the wireless-sensor and control-network space has been about the network stacks, radios, and microcontrollers they are built on.

This is where the problem starts, because you have a microcontroller developer on one hand charged with the task of creating a thermostat, but the network really becomes meaningful when a programmer or an enterprise can manipulate it and put different applications on top.
