I've seen your PM but you'll have to wait for it... don't worry, only a couple of days! 
Until then, I'd like to know about your experience with Digimesh because it seems not to be ZigBee compatible (as you can read in the white paper Digi published about:
page4/Interoperability)
It shouldn't be very important (though Zigbee points to be the next Bluetooth) but, as any Arduino follower, I do hate propietary protocols >:(
I hope the firmware version I'll send you to be compatible with. I haven't tested it since I haven't anything Zigbee compliant.
Even more, it seems to be a way to "flash" my old Series1 to have Digimesh capabilities.
Seems not very sure :-? Working on it.
