ZigBee news is starting to appear. ExtremeTech talks about an Open House session at a ZigBee Alliance meeting. The combination of low-power wireless, and ad-hoc mesh networking along with low-power sensors, and RFID is demonstrated across a number of applications.
Atmel and Ember are also forming a partnership to combine Atmel's flash microcontrollers, with Ember's wireless systems. Should provide a good building block for development of further products.
