I've really been considering getting one of those wifi mp3 streamers for my stereo, like one of these:


Of course, I'd prefer something that streamed ogg files, being the geek that I am, and obviously it needs to be able to connect to my Linux box. The above seem to rely on some kind of software running on a Windows box.

My questions are
  1. Do either of these work with Linux?
  2. Does anyone know of any that work with Linux?
  3. What's the sound quality of a unit like this?
  4. What other options do I have? (ie, something like a linux box w/ remote running Amarok?

Apparently HP is planning on releasing a Linux version of the above, but it's twice as much and not due out for several months.
