I want this feature so badly. I listen to 30+ podcasts and it would be much easier if I were able to do at 2x playback speed. I propose implementing a full range of 0.4x -> 2.0x so users can slowly acclimate themselves to the faster playback. There's an Opensource library called ScaleTempo which provides this functionality. http://scaletempo.sourceforge.net/0/ playback of audio and video at faster or slower speeds without changing pitch (i.e. no chipmunk effect)..
