Also, maybe ZigBee is not the best option here if speed is relevant (ZigBee migth add up to seconds due to Mesh network routing), XBee Series 1 (802.15.4) are faster than ZigBee and the configuration is similar if you want to deploy a star network."		**"I would try with routers and sending a unicast to each of them instead of a broadcast.

			*might try using GPIO pins on xbee radio to avoid using serial communication
			**need to use 330 ohm resistor + 3.3V zener diode to drop from 5V to 3.3V for each pin
