I purchased a hardware development kit from synapse-wireless.com. They make a really unique zigbee platform that runs python byte code quasi-natively. I am really amazed with it so far. It is very nice when you come across a product that actually does what it says it will. The wireless range really goes 75+ feet and it really does turn on in 100 ms. It joins the network within another 100 ms. By comparison it takes 300 ms for the human eye to blink. That means it powers on and connects to the network faster than a blink. I hope to post some examples soon.
