Yours trully unexpectedly ended up talking at WLAN Professionals Conference Europe 2015 on a subject of IoT and Wi-Fi. I heard good feedback after the session, so you might be interesting in watching 16-min video yourselves. (Disclaimer: presentation on my own behalf and may not reflect the official position of my employer). If you find some context in my video unclear, you might want to view the video of David Coleman, as my talk was largely provoked by his presentation (the current state of IoT allows for more than one perspective on things). Let me know, what’s your perspective on this matter in comments!
BTW, it was my second time there (and a second ad-hoc talk) at WLPC EU, and I absolutely enjoy it. If you reside in Europe and you are into Wi-Fi, you want to be there next time! There were many interesting sessions at the conference, you can view all the recordings here: https://vimeo.com/keithrparsons/videos
