John your wireless plug adaptors are a great idea. I currently turn off an old surge protector (with a dead battery backup) that I get free from work when the battery dies. these are much more "protective" than the traditional power strip. However, I have to bend down to access the on/off switch under the layout.
With your idea, I can add these wireless switches to my wall plugs. I am actually using a few wall plugs, in different locations around the room, which are connected to two different circuits. This will save the "bending down" to access the power strips under the layout, lying on the floor. I also like the idea of cycling only one transformer to repair a trip due to a derailment. I currently have to turn the entire layout on/off, which is not always desirable when multiple people are working the layout. Its hard to hide your derailment (usually an operator error) when you kill everyone's power, and they have to re-start their MTH engine.
