Implementing Zigbee is more expensive than Bluetooth. ZigBee is also in a a somewhat chaotic state, the standard is nowhere near as mature as Bluetooth. ZigBee is also GPL in compatible with it's current licensing scheme. That said, ZigBee is my second choice. I'd probably ignore ZigBee and use 6lowpan instead. > > -- Jon Smirl jonsmirl@gmail.com
