A while ago I looked over the same fragments and bought two Xbees and tried to do it. I could never get the Xbee UART to work with 1wire and haven't touched it since. I'll probably not go back to Xbee/Zigbee unless they make mesh networking much better. Last time I checked Zigbee doesn't support it and Xbee has a proprietary setup that requires boards to be always on which makes it unworkable for low-power situations. My next approach is actually WiFi. There are these wifly modules with a xbee footprint: https://www.sparkfun.com/products/10822 They talk wifi and have much the same ports as the Xbee (UART, ADC, DAC), so you can also do a bunch of stuff directly without 1wire at all. They also support a mode where the connection is initiated by the module. So you can have a server on AC power and have the battery powered module periodically connect to the server. Whenever the module is not talking to the server it powers itself down to a very low consumption. Make the cycle long enough and you can use this for low power situations even though it uses Wifi. I see that Xbee itself has wifi modules now: https://www.sparkfun.com/products/12569 So maybe those allow the same kind of setup as well.
