I watched a presentation on this chip at Strange Loop 2013. Unfortunately, the whole presentation was a sequence of "look at this cool cryptic programming trick I can do on this chip" by Chuck Moore, without a single legitimate use case outlined. It made the design look needlessly complicated to use and really didn't answer the question of why the chip is actually useful or in any way better than existing low-power microcontrollers. That says more about Chuck Moore's lack of marketing abilities than about clockless designs, however.
