Arduino 101 intel curie nRF51822

Hello,

Arduino start selling Arduino 101, powered by an Intel Curie processor.

As far as I have seen here, Intel Curie module integrates nRF51822.

I was wondering how we could use deeply the Intel Curie, behind the arduino part, implementing a RTOS which will be released this quarter.

I was also wondering how the nRF51822 is implemented in the Curie Module, I expect it to be interfaced with the Intel CPU on an UART link. That's meaning that this nRF51 is just used for the BLE part, and we could just program an OS on the Intel chip part.
