I doubt it, at least in the near future. When travelling with young children/babies, we routinely get routed to an otherwise blocked, WTMD. A NoS is going to have a hard time with an adult holding a baby, or a young child that won't understand how to stand and to stand still.

Also, a NoS requires two TSOs working simultaneously to function (with the existing privacy protections). Recently walking back through security to get a forgotten item, after the last flight had departed from the terminal there was only one TSO working the station - he did the x-ray on my wallet, and walked me through the WTMD.

I'm sure a NoS could be designed to cope, but I still give that a reasonably long way off.
