I love Shepard Book, I almost answered him for the previous question of who in history I would want to spend a week with.
I'd have to go with Mal, I think they are all fantastic and is what made the show so great. Sheppard would be a close second.
I think IoT is fantastic for creating new and unique ways to take advantage of technology in creative ways. Unfortunately most IoT has no respect for security.
I have heard of smart locks specifically designed for showing houses. Now that smart locks are more common you don’t really need anything unique for real estate.
Solid choice on Mal! And thanks for your reply!
