In order to stream to squeezebox players (including the one on the
Touch) an analog intput had to go through an analog to digital
converter (ADC), there are no stereo ADCs on the Touch. The DAC chip
which drives the internal speaker has a an ADC but its only mono, AND
its not hooked up to anything, it would take some external electronics
to make it usable. 

As BPA mentioned the only way to do this is with a USB box that does
ADC. The Touch support generic USB audio drivers which can work with a
number of these ADC boxes very well. The fun part is getting software
running on the Touch that will read that driver and do something with
it.

As I have been poking around the guts of the Touch's audio processing I
have run across "capture mode" which looks like it maight actually talk
to a device input. I'm not sure anything does anything with it, but
there does seem to be some sort of low level support. There would have
to be something in the server and slimproto to support that and I don't
think there is at this point, but I could be wrong about that. 

It will take some more research.
