A version that is a real fully functional high resolution camera. Once they work out all the software algorithms you'll be able to see all portions of the image in focus at the same time. That's what they're working on next.
Yes, but stacking is a laborious process. Really detailed stacking requires a completely still subject (think dead bugs) or the automated algorithms inherit ugly artifacts. Conversely, manual stacking is very time consuming. I generally manually stack no more than 2 or 3 images, whereas deep stacks of dead insects can be composed of hundreds of images.
