Hi.

With OpenAL Soft, there's the ALC_SOFT_loopback extension which has the 
audio samples written to your own buffer on-demand, instead of to a real 
sound device as-needed. The only caveat is, on Windows it can't be used 
through the router since it doesn't know the new open method and won't 
recognize the device handle, so you need to call the methods from OpenAL 
Soft's DLL directly.
