CTIS has been a thing in military contexts (lots of transitions between terrain types and lots of available labor to perform maintenance) for a long time. It only makes sense that it eventually transitions into other contexts where it's beneficial and there's a lot of labor available to maintain the systems. This particular system sounds like they found a way to stick a rotary compressor (think automotive A/C compressor) and the requisite CTIS gear into the space of a bike hub which is a non-trivial accomplishment in mechanical trickery if they did manage to do so with adequate performance.
