I was thinking, you gave a specific example and I suggested that isn't a typical situation. We've already discussed why it's possible that #14 wire going more than 45 feet could be marginal, complete with real numbers. I doubt there's any argument that you can run a switch machine, or a dozen of them, using #14 wire. I'm at a loss as to what technique you refer to, a dangling wire from the ceiling probably isn't what is desired here. 
Think, man, think.
