Great list.

I would add "Edge Device Applications" as a new entrant to the IoT software marketplace as well. Platforms like PTC ThingWorx, GE Predix, MS Azure are essentially becoming app stores for edge industrial devices where developers can create applications for IoT nodes/gateways.

Also ML/analytics are starting to enter the equation as companies try to figure out how to optimize the tons of data that is being pushed through IoT networks, and feed it back down to improve processes.
