audio drivers that used callbacks -- so for some sorts of applications,
at least, its a pretty straightforward retrofit. The sfront changes were
done in preparation for Portaudio (now in sfront 0.75) and CoreAudio
primarily, but hopefully JACK support will happen too, especially if
someone is interested enough to write an sfront audio driver and
contribute it. See:
