We actually considered creating a separate iio_dev per "virtual" sensor (pair of {sensor, rate}). The problem is, they can pop-up dynamically and even if we opened a backdoor interface of silently creating new chardevs, we can't eat up all major numbers in the system. And we can get dangerously close to that :-(
