Oh boy, what a friggen teaser!!!!
Reversals at home are not difficult, as I have been doing them for about a year. Anyone that has been doing E6, it would be a walk in the park. There are no temps to watch either.

More votes always appreciated.
My personal belief is that a screen-plate product would thrive in this world of scanning & sharing photographs electronically. Their weakness was always the inherent irreproducibility. I think the current darkroom culture, particularly people who love developing their own b&w film, would get behind this as an opportunity to make color pictures easily, with normal b&w techniques.
I'm in the process of plumbing some pipe dreams... I hope someday it'll be possible to turn on the water.
Start with a Dufay type film then, and work up!
very much in favour of this and have been discussing autochrome and dufay with a couple of clients into alt-process.

I want 6.5 x 9 cm glass plates!
Using film since before it was hip.

I agree Ron; I just use Autochrome in lieu of screen-plate, which no one seems to know the meaning of! :-P
In reality, what I have in mind is much more inline with a Dufay type screen. Though Autochrome's stochastic pattern does give it advantages over ruled lines.
Don't worry, no potatoes were harmed in the making of this film!
Interestingly enough, I have seen Dufay and Autochrome side by side and the Dufay is much better at all sizes but the Autochrome seems to fall off below 4x5 in image quality.
Interesting indeed! Well that just goes to show you how much I know.
I posted a really cool Dufaycolor photo I just found.
I'm gonna see if I can find a measurement of the color elements in some of these systems. I'm sure I've learnt such things in the past, but I always forget...
In our private convo's, you mentioned that dichromated-gelatin is no good for making a screen due to its resolution. But if I may counter, DCG has some of the highest resolution of any photo-sensitive substance; afterall it's used in holography. There's one method for screen formation in particular (du Hauron's original proposal, though refined in 1862(?) by his brother) that I have my mind set on.
Grains are from 5-10 microns, 1700-2500 grains per linear inch
Spacing of red lines = 533 lines per inch.
240 filter squares per square inch

Each circle was 1/400 of an inch wide
