问题
I'd like to tag something important with a ZigBee sensor and be able to know/track its approximate distance (ideally location, but I understand that would take many reference sensors) through my Android cell phone and alert me if it moves out of range. Alternatively, use the cell from to locate RFID tags (I know the exact location isn't possible, but looking for +/- 5-10M).

I've been testing these SDIO ZigBee cards for a while: http://www.spectec.com.tw/sdz-539.html Although I haven't still managed to make them work in Android. But to be honest I've pushed the project aside for the last months :-(
Hope it helps. I would appreciate it if you could drop me a line if you find a solution or manage to use these devices.

rfid+zigbee used for location monitoring
First and the for most thing that has to happen is that, android phone has to support zigbee. This link shows a zigbee enabled android phone.
Another link: zigbee enabled android phone
The most important aspect of your question is that, the smartphone should act as a end device (node) in a zigbee network. Then if node ( smartphone ) moves out of zigbee network then it will be sensed by co-ordinator .
