This looks like a cool home automation Kickstarter project, that could potentially make home automation lighting control cheaper and better. So instead of controlling lights by changing out the switch, now you could just potentially switch out the bulb. One bulb connects to Wi-Fi and the other ones connect to it via ZigBee. Its just not real clear which bulbs have Wi-Fi or if some type of Wi-Fi to ZigBee bridge is required. Looks interesting.
