I'm the OP... and yep we're referring to the same thing. It really is completely tool-less... Thanks for the video.
I should explain, I study mechanical engineering and I find this stuff very interesting, intriguing even. I'd think the bending at the hub-freehub connection from chain tension and axle deflection (from bumps and pedaling) could throw things off. Maybe there are enough bearings and tight enough clearances that a pop's worth of pressure is all you need to keep the whole thing together. Either way, it works.
