The last time I looked at Zigbee it looked expensive to do, hopefully 
I'm out of date and this has all changed:
 
I think the Microchip Zigbee stack is the only "free" one out there in 
terms of code. It's license is not an open one in fact it's got a use 
with Microchip Products or else clause. So you'd want to stay clear of 
it. It probably wasn't that useful anyway, especially if there's any pic 
assembler in it. (If you are using a Microchip transceiver even with an 
different micro-- it's a good as good of as anything else to port to 
your platform/BSP for your own commercial use.)

The standard itself isn't free either unless you're using it for 
"non-commercial" uses. I honestly don't know if contributing to an open 
source project and then using the results would be a commercial use.

I'm not sure what the "Control4" company that linuxdevices.com finds 
uses but I suspect it's probably a commercial one. (I think a lot of 
early adopters may tend to use complete modules not chips as the analog 
stuff can be challenging-- which could be why there's not much code out 
there) It's the only other open source reference to Zigbee I see..

Best,
