Hmmm . . . interesting and . . . uh . . . unique . . . thread, though I wonder why the OP was suspended. Though this is a somewhat delicate topic, it's an important one for travelers.

The new Chongching toilet reminds me of the "pissoirs" I used to see in Paris. They offered a little more screening -- only your feet were visible. I tried one once for the novelty value, but was somewhat -- inhibited -- by the openness. I can't imagine being particularly comfortable with the new Chinese innovation, though necessity may easily override any embarrassment.

As for Chinese toilets, China, of course, isn't the only country to use "squatters," and I've encountered seatless-toilets in Sicily and other parts of Italy which pose similar logistic issues. After many visits to China, I've decided that the only answer to a squatter is "practice," and it's a skill I'm not particularly eager to acquire; there are usually alternatives to be found. It's always a good idea to carry tissues wherever you travel and may have to depend on public facilities (this is equally true in Europe and America). I've seen squatters at the airports in Beijing and Shanghai. Two tips for China: the "handicapped" stall, when available, is always a "western style" toilet, and many public restrooms in China have a single paper dispenser mounted outside the entrance -- if you don't carry your own tissue, check there before availing yourself of the facilities.
