So I contacted Photo Researcher, the guy who made that coating machine and is quoted in post #1. He told me that he's working on a Kodachrome-esque color film; and like PE, has successfully created the 3 emulsions necessary but has yet to "put it all together". It sounds like he is working very hard on it, and he isn't too fond of computers but hopefully he will drop in to share his progress from time to time. I encouraged him to do so.
