Hey I am wondering if there is a thing you can plug into a stereo receiver thing that has a wireless link to it. Other then the things for your ipod that broadcast the music on a radio frequency.

My problem is that I have a laptop and I have a Receiver I want to be able to play a song on my laptop and have it broadcast on the speakers that are plugged into the Receiver without having to plug the headphone jack think into my laptop. Any ideas?
