I suspect they're either speaking broadly, or thinking in terms of having sensors in everything, always reporting readings. Their tech doesn't seem particularly suited for interactive devices, because the protocol requires the device to poll the network and see if there are messages waiting for it. Edit: Also I'm fairly certain that WiFi will choke long before you get close to having 500 devices in an area the size of a house.
