Mustafa, I don't think there is any problem figuring out what's in the pods... certainly, we can break open a pod and do spectroscopy and tell you exactly what's in there and in what proportion. We probably already can guess the most important ingredients based on others' monobath work.
Even deciding which film best approximates what was used may not be such a challenge- there are so many rumours about it being panatomic x that we could just say, fine, close enough, let's call it that. No need for me to throw it on a TEM or whatever and prove it so.
But then what?
The issue is the reliable production of the packed and podded film with QC at the level of Polaroid... or better yet, the level of Kodak or Fuji. Based on what reading I've done, I would conclude that getting the polaroids to shelf at reasonable cost, in mass quantities, and with acceptable shelf life and QC is by far the hardest part. The formulas have been known for a very long time by two, maybe three companies.
What disappoints me is that polaroid has yet to step up and say, fine, we hereby discontinue the film as a packed product, but we will release the emulsion formula and the goo recipe... I mean, formulary could probably make up a goo and sell it in nothing flat, for use with a variety of films and processable by relatively simple rolling mechanisms. It disappoints me that polaroid didn't see that the true value of the product is definitely not in the positive image- it is in the quickly developable neg. For this they will face the wrath of St. Ansel himself on Judgement Day. And Ansel's gonna be pissed. I think he's going to place them on zone 20 or so.
