I saw that a few days ago, looks promising but the price will need to be competitive. It would save about 1 to 1 1/4 inch per surface of walls and ceiling compared to clips and channel. I also thought about two layers of DW. From the picture it looks like it is designed for a single layer. I wonder if there is a work around of using laminating screws for the second layer making sure you don't hit a stud.
