RF4CE spec released
We should begin to see RF remotes replacing IR by year end, with the ZigBee RF4CE spec now available for download from the Alliance site. This whitepaper has just been released: http://www.zigbee.org/
This new presentation is also a good overview of the current state of ZigBee, detailing RF4CE progress as well as Green Power, Healthcare and Enhanced Smart Energy: http://www.zigbee.org/
There's even a proposed mockup of how the first RF4CE profile may look (ZigBee Remote Control).
