What HA software have Cocooners found to have the lowest WAF? I want something that my wife would also use (via the 15" wall-mounted LCD Touchscreen in our bedroom). Keep in mind the correlation of cost on the WAF 
Right now I have a combination of Insteon, basic-x10 and Smarthome-x10 (2-way and scene capable) controls througout our house. I also have the x-10 controller for our Honeywell alarm system (sends x-10/relay commands based on alarm/sensor events and schedules).
I'm only looking for basic functionality for now.
