Not to mention that AUDIO_RATE_CONTROL would completely useless in JACK?  
You'd have a buffer-full of samples and apply frequency shift to them, which would change the length of that buffer, which you couldn't give to JACK unless you do some rebuffering.

Correct me if I'm wrong.  We have similar issue with ecasound's Pitch Shifter operator in connection with JACK.
