Excited about Weave. Not sure about Brillo. It is unnecessary. Most IoT things are low power Cortex-M devices that need to do very little and are very low power consumption. You don't have SDRAM, or a fancy OS and don't need it. There are plenty free and non-free RTOS available for those chips for whoever needs them.
