anyone know if an FM modulator ( like whats used to link ipods to hi-fi)can be adapted to stream audio to my hi-fi in the room next door?

i dont want to run cables, and dont want the expence/hastle of a wireless network...and i really wanna use my pc as a jukebox, cos ive built up a ridiculously huge archive of mp3's...ive got quite a good hi-fi set up, and it seems kinda wasted by not hooking it up to the computer.
