Sounds great. Currently, poor security is the bane of IoT devices. I would suggest the industry put all effort into efforts to improved security and privacy features of their products. Security is the number one reason I am reluctant to have internet accessible devices in my home.
Does restricting IoT traffic to the local network mean we lose the ability to leverage the analytics or the analytics become too simplistic to be useful? Will the majority of consumers, the mass market of consumers who we need to make any product category viable, want or need to have a mini data centre in the home to manage all of this? I don't know.
