If a color screen-plate product (like Dufaycolor, Autochrome, etc.) came to market today, would you use it?

What format would you prefer it in? How fast would it have to be? Would it have to be film, or would you bother with plates?

Would you be content with the one-off original? Would you go to the trouble to reversal process or would you process it as a negative? Would you scan it or attempt to print it on RA-4 or Ilfochrome?

What price point would seem reasonable to you?
