Right out of my head, so take it for what it is:
1. Use APUG as a repository for ways to make the different processes available, in their technical and artistical aspects.
2. Open source and if possible reverse-engineer needed things.
3. Gather more information, and use that as a base to maintain or improve the analog. Especially when it comes to practical "how did you do that" this is vitally important. As with the Autochrome, there are many things we take for granted in our ways of handling film.
By discussing (sometimes endlessly) different approaches, we keep the knowledge alive. But I also believe one should ask oneself: how much time, money and tinkering can I spend on the things I am interested in? I am prepared to go back to wetplate stuff. I think there are quite a lot of people who rather would get out of it alltogether, if it came to that point.
The real problem is that digital is wiping out the whole analog ecosystem, and I mean just about everything, from cameras, filmholders, film types, storage solutions and a huge amount of things one really don't think about until you talk to some foppish salesperson who declares the things you want dead, gone and not even worth looking for. We need to save this ecosystem, or else make a new one, with the knowledge and user base that we have today.
