Tim, I am afraid there is not much out there, as Mark always likes to point out. However, there is an awareness growing, and I can hope that the under thirty crowd might embrace the technology, as they have all grown up on headphones and few listen to plain old stereo. They might begin to embrace the technology, and there are also hrtf programs and what not that try to simulate binaural. True binaural is a dummy head with mikes inside each ear, and then from each mike it goes to an amp and to your headphone, short, sweet, and sounds best with absolute accurate electronics.....binaural is extremely accurate as a recording process and the ear will not accept the kinds of "preference distortions" plain old two channel stereo engenders.
I think it helps folks to understand that the deficiences of plain old stereo are just what they are and that modification of the stereo effect is not all that bad given the weakness of stereo. No one I know of in our club who has heard binaural thinks the same way of plain old stereo any longer.
