I think a point is being missed here. Any digital file can be edited!
Just because there is not a readily available cheap commercial product
for that particular file does not mean the file can not be edited by an
expert. In the old days when software was sold on floppy disks, and the
companies kept coming up with protection schemes to keep you from
copying the disk we (generic we --while I wrote such a program myself in
Z-80 machine code, I did not make it publicly available) developed a
program that would copy the disck bit by bit including the copy
protection part, or would allow you to edit particular bits on the disk
to eliminate the copy protection.
So if someone wanted to produce a camera-raw file that had bogus
information in it, it would not be a difficult problem. And once done
there would be no way in the world for anyone to prove it was not an
original file except by a confession by the person who had edited it.
To so many people software is some kind of magic. It is not. Almost
anyone can learn to write it and edit it if they are willing to make the
effort and take the time.

I don't see it in CS2. Remember, too, that RAW is a generic term. For
Nikon you'd have to save the file as a (non-demosaiced) NEF file. For

Exactly, 'RAW' usually means it is pretty close to the internal format
that is used either by the hardware (as in DSLR's) or some software
like photoshop.
AFAIK, there is no software yet that will convert some generic image file
like TIFF or JPG to one of the RAW formats normally used by cameras.
It would be hard to come up with real advantages for doing that
apart from trying to fake someting :-)
The advantage in using some kind of RAW format as output for
digital cameras is that LESS processing is required in the camera
which could make it faster, and also that the needed conversion
with regard to color and de-mosaic can be done on a powerful
system, and could be retried to get the optimal conversion.
The conversion usually LOOSES information in this step,
so if you just have a single opportunity (in camera) it has
to be perfect each time ...
Ah, okay.
In Photoshop 7, 16-bit files have three save options: PSD, TIFF, RAW.
I've never bothered with that RAW since TIFF was always industry
standard.
The 'RAW' used there is probably a format that closely matches
the memory-structures used by photoshop internally.
