Wired my wife's Doll-house in a foil-type tape circuit, that sticks to the wall. Turns out they make a UL version for real use! Haven't seen any, and not sure I want to.
Also covered in art. 324. Flat Conductor Cable. Not permited in resi or hospitals.
Any way the only idea I like is : "use the opening in the wall to run the wiring through the studs and reserve the wiretracks for low-voltage."
Now if the Wiretrack people were smart, they'd make the stuff in 14ga steel, and get that listed for resi use.
