Thanks for various responses to my original Zigbee question ...

Had a quick scan of the XBee Zigbee manual (as opposed to 15.4) and it 
would appear these modules don't support sleep mode for "end devices" - 
is this correct, and does it therefore mean that XBee isn't suitable for 
mesh networking with battery powered end devices?

Does one have to buy membership of the Zigbee Alliance to use these (or 
any other) modules in a commercial product? The ZA membership FAQ 
suggests strongly that this is the case:

*"Q: If my company uses a ZigBee module in my product, do I need to be a 
member?*
A: Yes."

Are all commercial XBee users coughing up $3500 to ZA?!
