A filtering hook is already provided through the audio sysfx mechanism and this 
is in user mode. I believe the root problem in this particular discussion is a 
difference in the desired business model. The audio sysfx mechanism is designed 
for effects either as part of a device driver; developers of DSP should partner 
with OEMs or audio device manufacturers. It seems however that kevinrich47 
wishes to deploy his DSP as some sort of independent product.

Just one more request that would benefit from a user mode audio I/O hook.
Is such a thing in some list of future features to consider? If such a list 
exists, this should be there with a high rank, IMO.
