<p>I myself am looking around at building something similar. My idea (and I 
don't know how far-fetched it is) is to take an unused portable CD 
player I have, and 'intercept' the data line that goes into the DSP. 
Thus, I would write an ogg stream onto each track of a cd. When the data 
comes across the line, the ogg vorbis hardware would decode it and send 
it to the dsp to be played. Obviously I would have to deal with CD speed 
and buffering issues, but I think it has a chance of working. Since this 
would be a one-of-a-kind device (and just a hobby) I was looking for 
something cheap and easy to work with. Someone mentioned an XScale dev 
board, so maybe I'll take a look at that.

This doesn't suit my needs, but would something like this, running linux 
and with an audio card attached work for the other guy?
