I did this once as a teenager... I simply put a battery on a long wire, with
an IR led on one end, and an IR detector on the other (radioshack pair)...
(use resistors as needed for the LEDs.)
incoming IR on the detector would turn the LED on and off... a simple relay.
I have no idea if it would work with more modern IR remotes, but its such a
simple circuit you might as well spend the $2 in components, and freeform
