A few weeks ago I bought a Griffin RocketFM Transmitter, a super-clever USB gadget that allows me to stream music from my desktop machine (in my office) to my living room stereo system. It works perfectly -- I can listen to KEXP, podcasts, what-have-you. The fidelity, I'm sure, isn't what you'd get from a dedicated media hub, but for $29, it's a heck of a bargain. Recommended.
