Some of this data distribution may be addressed by the cluster driver logic in the OS. Bob Feretich added this a long time ago, but it has seen little use. See: https://github.com/apache/incubator-nuttx/blob/master/include/nuttx/sensors/cluster_driver.h https://github.com/apache/incubator-nuttx/blob/master/drivers/sensors/README.txt#L49 The Sony Spresense offers a a hardware solution that also distributes sensor data. Ideally, we should take one driver model and extend and enhance it rather than re-inventing it periodically.
