One thing that comes to mind is the small gumstix modules.
It may be a more expensive solution than you have in mind, but the
advantage is that you get a *tiny* little computer pre-loaded with
Linux. Add the audiostix attachment and you get stereo audio in/out.
Or the roboaudio, which has an on-board Atmega, will give you some
10-bit analog inputs for sensors.
But yeah, it's about $100 to $150 for the motherboard and $40 for the
audiostix expander, so this might be out of your price range. Also
add a few more $$ for the ethernet module. Anyways, worth looking
into. I've played with them a bit for a sensor interface, and it was
lots of fun, and way easier than building it myself. Never got around
to trying the audio side of things.
