When will you all be posting more information about the hardware module? I'm curious about the specifics of the hardware, (basically datasheet stuff for those of us actually designing hardware):

* supported voltages: 5V, 3v3, 1v8, ...?

* module communication: SPI, i2c, TTL serial, etc.

* module programming: sounds like there is a way to load my key on to the module, will that be done through the attached platform? Or will you need a proprietary programmer?

* footprint for the module: not only dimensions, but keep aways (antenna, etc), orientation, etc. And from the website photo looks like there are no mounting holes on the pcb, and those are especially handy when prototyping

* external antenna: I realize this throws a monkey wrench in the FCC cert, but there are going to be applications where an external antenna is going to be a necessity. Any plans for an external antenna module?

* EN pin: the Iq on many of these radios make it necessary to completely disable them for extreme power savings. Be curious how quickly the radio module can cold boot and establish a link with a base station.

As for the network, no mention of communications with the devices, strictly one way? No ability to push updates to sensors in the field?

I'm missing a couple of others, but I'm too braindead to think of them at this hour.

This looks like it could be a huge time saver for those looking to build out sensor networks, I hope for your success!
