Converting analogue source to digital stream on the fly

For example, you need to use a Wolfson/Cirrus custom version of Raspbian because Wolfson/Cirrus hasn't yet integrated the drivers into the main Raspbian build. "
I can see how it should be possible to use it to record from an analogue source, but what about live streaming? Would MinimServer/MinimStreamer install ok on the modified OS? And, assuming they would, is there a way they and the output of the card could be configured to, as it were, talk to each other, ie MinimStreamer relaying the output from the card to the home network? For example, might it be possible to set a folder on the sd card of the Pi (or on an attached usb stick) for the soundcard to record to, and have MinimServer playing the file in that folder as it's recorded? (As I'm sure you realise, I'm out of my depth here!)

MinimServer and MinimStreamer can be installed on the modified OS and they support playback through the Wolfson card if a suitable UPnP software renderer is running on the Raspberry Pi.

There isn't any way to feed the ADC output into MinimServer or MinimStreamer. I have never attempted to do anything like this. MinimServer can stream disk files and MinimStreamer can stream HTTP network streams. A live capture stream from an ADC is neither of these.
