Robert - maybe you can answer a question about Leviton's dimmer switches that I don't quite understand. Looking at Leviton's catalog, I notice that quite a few of their switches (including the 16383-WI) require a Neutral connection. I've checked the wiring at most of my switch locations and only two wires are visible.

Why do these switches require a neutral connection? Also, if my house wiring doesn't provide the option, what Leviton dimming (and/or non-dimming) switch would you recommend?

One other quick question. In two locations in my house I have dual switches controlling a light (top and bottom of stairs). Will Leviton's remote switches work or will I need to run a control wire (something I'm not too keen to do).

Thanks in advance!
