Maybe you're supposed to set it up over your campfire for warmth????
Seriously, I can't see how that tent is a solution. I'll bet no one got rich on that invention. But maybe I'm wrong. People use those hammock tent things. I remember a couple buddies of mine used those hunting one year. Granted, they did so as a favor.
I've got to sleep on my stomach at times. No way can that happen in a hanging tent.
Remember as a kid sleeping on a trampoline with friends? You'd wake up in the morning and everyone was packed in middle compressed together. That's got to be how this tent would be, right?
