Yes, there are several projects underway for the "Industrial Internet" where v6 and small footprint devices intersect. The Term "IoT" is a marketing thing. In fact, Cisco now calls it the "Internet of everything". So, as M2M applications become more prevalent, the erm will be replaced by something else.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
