Total Intubation

User Ropenbag posted this hood on his Tumblr the other day....the hard-core breathplayers came out in force to find out more about it, however the details are still elusive. I have done serious nasal intubation a few times before, and the totality of face-filling of this hood is amazing. I can only imagine what it would feel like to have nasal cavities and mouth completely filled with what looks to be silicone and secured in place with latex. I would really like to find out more....the tubing and mouthpiece both look to be silicone; I would imagine this hood wouldn't be too hard to develop with the right moulds. Any thoughts?
