I did indeed. The idea that's been thrown around in the past were 
"shims" so you could shimmy (ha ha) your own callback into the stream 
between two channels and effect changes on the audio frames. You could 
in theory do it by forcing all channels through a signed linear 
translation path, and putting the shims in between there so that a 
callback always gets signed linear and then the returned frame is the 
one actually returned from the translator.
