OK, I'm still looking for the camera. It's not April 1st yet, is it? This is just silly...
I can see advantages regarding the distribution of power, but to say it can be hidden by "a little spackle and paint" is somewhat limiting. What about walls that have wainscoting or wallpaper, chair rails or other obstructions that disallow the wire to simply be laid on the wall and covered up? What happens when you want to move the object you're connecting?
This is another great example of media hype.
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.
