Microchip now provides an 802.15.4 radio chip
Microchip Technology, the only company providing an open source ZigBee protocol implementation, has now released their first 2.4 GHz radio transceiver. The MRF24J40 is intended for the 802.15.4 chip market and can now be used with the company’s zero-cost-license and royalty-free protocol stack, which is also one of the smallest in the industry. Source Code availability means designers can customize their product, using more than 200 of the company’s compatible PIC MCUs.
Moreover, the company also freely provides MiWi, a small-footprint protocol for customers who do not need ZigBee protocol interoperability but want to use 15.4 transceivers in low-cost peer-to-peer, star and mesh networks.
The ZENA wireless network analyzer tool further assists in the design process. A combination of software and hardware that sniffs packets from top to bottom.
MRF24J40’s samples are available. Current purchases shipping is expected for March. More info at Michochip’s website

But their ZigBee stack is no way near open source. The source code is hidden behind a Windows installer that prompts you to accept a very restrictive license.
Not open source.
