Heyas folks --

I'm wondering if there is any interest in a pseudo audio device driver 
that does nothing but push raw PCM data back to userland.

I discovered the rtunes project ( 
today, which transcodes WAV and PCM data to Apple Lossless Audio, then 
pumps the data to an Apple Airport that supports AirTunes. So that's 
kind've cool, but I need to either pipe PCM to the rtunes application, or 
modify existing applications to use the rtunes support library.

Instead of this, I wrote a simple audio device driver that pushes raw PCM 
back to userland. It allows me to redirect the PCM data written to an MI 
audio device back to userland, and I fed this data into rtunes for 
seamless operation with any audio consumer.

So, I ask -- is there any interest in this pseudo-device driver?
