I'm pretty forgiving about accessibility (I'm able to say this at all because I don't have to rely rigidly on accessibility tools) but nav menus feel like a baseline we shouldn't muck with. Tabbing doesn't seem to respond very well in the live example, and at least in the limited demo you can't expand the listing without using a mouse (I thought it would respond to a space with the :checked pseudo, but seems not).
