What's the deets on the Cortex-M3? Is that accessible to the end user, or is that blackboxed and NDA'd? (Cough cough, IPM... >_>!)

How's this stock up to the BBB as far as power usage goes?

What's the supply chain look like for your silicon? Planning to maintain stock at the distributors?

Any plans for a non/through hole? Exposing the ethernet and MDIO pin headers for another SD card would be awesome. (Props for putting USB on the headers, and keeping the underside empty!)

Edit: Looks like you're planning more on using this as a demo-board for your chip. Does powering the chip from the LiPo handle the RTC, so I can stop dropping a DS1307 onboard? ;)
