Seems like an interesting topic - kind of like customer approach to IoT connectivity. I firmly believe this area indeed requires much more attention than what it is given currently.
We have touched the similar topic from a slightly different angle - we believe that manufacturers of the devices with connectivity capability should grade their products in a similar way white-goods are graded for energy consumption; this would allow customers to make an informed decision about the use cases and other controls they should be mindful of when using given device.
Our approach is presented shortly on our webpage. Do you have full slides from you presentation to share as well?
