Ain't gonna happen. The Plummer's UNION is on the case.
I have no specific info but i read about a case last year where where these waterless urinals were going to be installed (east coast i think if anyone is local to it). The plumbers union protested. They ended up installing the waterless urinals and paid for all of the actual plumbing to be run as well but capped of at the fixture.
And that's the truth. I read an article not to long ago (in all likelyhood it was posted on FR) and one contractor or builder (in Chigaco?) wanted to do this and he got holey hell from the union. They ended up compromising to have some sort of regular plumbing, too, in order to appease the union and to be able to follow through with their plans to build their own building.
