Adding "Internet radio" to home system

I have a typical component stereo system, of a vintage to include FM radio, but I wanted an easier way to hear internet stations on it than using my laptop. What an FM tuner is to a free-standing "radio", I assumed there would be an "internet radio" equivalent -- that is, an "internet tuner". But I can't find the product I have in mind, which I think would be small and cheap if it existed. As a substitute I'm using the Logitech Squeezebox internet radio. This isn't bad, but its remote cannot change stations, and the only output is the headphone jack rather than a Line Out.

So is there an "internet tuner" being made?
