The short answer is: No. I don't see how Bitcoin fits into IoT. We are working on the exact same usecase at IOTA (http://iotatoken.com), only our solution is scalable, lightweight and most importantly: there are no transaction fees.

If you have some reference code for IOTA, I'd like to see it. I'm firmly against any type of closed source Infrastructure code, so I'm hoping that's the plan here. I would also mention that we're not QUITE there yet with this stuff, so over engineering solutions to be scalable to trillions of devices is probably overkill. Giving a simple IOT device a small wallet to pay for its infrequent API calls is probably doable with Bitcoin, even with transaction costs. For other use cases, I can envision proxy devices with keys that represent the smaller, low power, frequent transmissions.
