@Duane: Yes, there will be places where cost sensitivies are such that languages like Java, Python, Lua, etc. will be fine. I'm more concerned for the billions of devices that will not have that luxury. Look at the cost differnetial between an ARM Cortex A8 and a Cortex M0. The M0 is less than a nickle and the A8 is several dollars. Multiply that by 40,000 sensor points and you've got a sizable chunk of change.
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.
