I am sure it is possible to have a camera that can show an exposure as it is
being captured 'live' (through the electronic viewer on the back), like
those inexpensive digitals that allow you to preview the shot in real time,
except that I would like it for long exposures. So if you were building a
picture by painting with light for instance, you could paint a bit, have a
look, paint another bit, and so on until the picture is finished. Anyone
else got any wishes, by the way if this already exists please let me know.

I think the Canon 20Da (notice the A) does just that.

The "a" in the model stands for "Astrophotography" -- the camera has a
number of features oriented to typical astrophotography needs, including
*very long* exposures. I think I read somewhere in its specs that it
shows you a real-time preview of how the exposure is doing, so that you
can decide when to stop (either because you got the exposure level that
you need, or because you have enough information to determine that the
exposure is ruined -- e.g., motion blur due to polar misalignment, or
overexposure due to a stupid car passing nearby, etc.).

Not sure if your description refers to multi-shots (from what I
understood from Canon's specs, this is a "single-shot" in very long
exposure, and you can view the "partial" result and decide)

That sounds like just the ticket as it *would* be a single exposure with
multiple flashes. I will be checking that out, thanks.

Why not shoot multiple exposures and then combine exposures in the editing
software?

That's one way I suppose.
