Great - "Problem" here is not the paper and gelatin - it's the sensitizer (Dichromate requires a police permit...)
Hmm, yes, that's a little bit more difficult to get around. But hey, if you need some, I could pre-sensitize it and ship it in a PVC tube. Funny, we have some carbon tissue that was sensitized sitting in the freezer in tubes and it works fine...2 years later.
