Are you kidding me? Making a drawer with four cuts on one piece of ply? Hot dang... I like it. Depending on cost, I would most assuredly have this beauty in my shop. I would hope it would come with the full dado stack needed to make the cut, adjustable for the various widths by adding or taking parts out of the stack.
I think I would want to tack the bottom into the sides for added strength, where tacks are not visible. Perhaps some pin nails along the corners.
I use half inch ply for drawer bottoms and sides, so no sweat there. If the client wants dovetails, I can do that for an upcharge. If they want dominoes, well, I ain't got one, so there would be an upcharge. No sweat at tall, unless the device is too expensive.
There's a TV show called Shark Tank or something where inventors present their device to potential financiers. Seen it once, and one of the devices presented is in stores.
