I think they've created a really interesting solution that's visually appealing and probably deals with the water dripping problem pretty effectively. From an architects/interior designers perspective I think they may be on to something. Less visual clutter in the room, fewer products to spec, etc.
From a systematic usability perspective, this could be a nightmare. In a high traffic restroom like a stadium, nightclub, or movie theater. this would be a nightmare. Having multiple "stations" helps keep the flow moving quickly, eliminating bottle necks. You already have to wait in line to pee when a movie ends, now you'll have to wait in line to was your hands too. It will probably just result in fewer guys washing their hands at all.
On the other hand, in nice restaurants, residences, or businesses, it may be a perfect solution. It doesn't have to be perfect in every environment to be a good design concept.
