As long as I'm off topic this morning...

Apple's ipod offers an accessory that lets you broadcast your playback over 
low-power FM to any nearby FM radio.

I know that this is by no means a new idea, or a new way to pipe music around 
your house.  Duane and I suspect others of you might know of a reasonably 
priced device that would do the same for the audio output of a Linux 
workstation (there, that's a topical save...).

Any suggestions?

(Apple is badly backordered on ipod stuff, I have a chance to get get in with 
a replacement here.)
