How do you run a wire through rigid insulation behind a wall?

My neighbor hung a new TV on his wall, and the outlet and components are down near the floor. He wants to hide the wires. The room is an addition on the outside of a brick house, and there appears to be 3-1/2″ of rigid foam insulation behind the drywall, in front of the brick. Any idea how he can run a couple of wires about 4 feet vertically down behind the wall, without cutting into the wall?

If you have access to the bottom of the wall, below it's bottom plate, or to the top of the wall, above the top plate, you can in theory bore a hole up/down to run the wire through. But such access is unlikely on an exterior wall.
A thought: If there is a window adjacent to the mounting spot, one could remove bits of the window, bore sideways to the set, and also bore down to the basement or up to the attic, from the window opening.
Cutting the drywall is really the only option. It's really not a big deal at all and will only take a pro 30 minutes or less to repair. I'd cut a section of drywall out about 3 or 4 inches wide, cut a groove for the wire and let the pro put the drywall back and patch.
Thanks. As I was writing this post it was slowly coming to me that cutting into the drywall might be the way to go. I was hoping somebody would tell me something miraculous, like, you drill a hole and pour a tablespoon of some benign household material onto the foam and it bores a perfect hole striaght down for you... no such luck...
