Speaking of this task of snaking wires around, I saw a really neat
method for retrieving the fish wire on TV a while ago:
They neat part was that they fed a string DOWNWARD into a wall
cavity. Then, to retrieve the string at the floor below, they stuck a
vacuum cleaner hose into the hole and it sucked in the string!
Won't work in all cases, but a neat idea.

Ball chain, magnet. String and large hex nut, magnet. BT,DT,HTTS.
