Umm, are you purposefully leaving out the silver chloride emulsion that Michael A Smith and Paula Chamlee are developing? Or did that project die? Last I heard it was still in a testing phase.
Its not on the street yet Will. I have no knowledge of its progress other than what Michael has posted here and on other forums. Its a very daring and hence risky move on their part to do it. Even if it doesn't succeed, they should be commended for trying to do it. But, I can't print on something that I can't lay my hands on.
