Help Me Get Music From Our Laptops To Our Stereo

Bingo thought this was worth mentioning said

So here's my situation. We both have laptops and often either are playing music from online streams or files we have on our various online systems etc. I have a Win7 PC, she has a Macbook.

The laptops are pretty much always on the dining room table. The stereo is about 30 feet away.

I'd love to find something that has a 3.5" connector that can sit on a shelf near the dining room table that connects wirelessly to something that sits in the entertainment center so we can have our music playing through our stereo instead of through our crappy laptop speakers.

Any suggestions? Or is there a better way to go at this?

I've thought about just running a hardwired cable but I really don't want a cable going all the way across the rooms.

Thanks!
