All I am going to say is everyone should listen to this podcast: http://www.matrixmasters.net/salon/?p=258 Also people should go watch The Union: The business of getting high. http://www.theunionmovie.com/TheUnionWeb.html Both of the movie and the podcast go through the research and misinformation fairly well.
I could see this being better as a video podcast (since it sounds like it will be audio only). I would have some interest in a podcast like this, since I'm not in 'the industry', especially if it were to venture into current development (which I know you didn't reference, and may be too restrictive).
