I think I may have seen the discussion to which Jim is referring, or, at least, a similar one. Situation was for a combination bathroom fixture, with, as I remember, a light, a fan, and a heater. Power first went to the three-gang switch. The GC had screwed up before closing up the walls, and was trying to get the homeowner to go for running 2 12/2's, one with the hot and one of the switched legs, the other with other two switched legs.
I pretty much said, "No way in hell!" About ten posts later, someone came up with abovementioned references. I don't remember how it finally came out. It looks to me like it probably meets the letter of the Code, but I still think it's wrong, wrong, wrong!
