Someone else will probably have better info than I
do, but I've seen people in the photo group talk
about what you want. My impression is that most
of them use "asset management" software and that
the software can find similar photos.

Asset management refers to the trend, started by
Picasa, I think, of assuming that people don't really know
how to use the file system. So Picasa would find all
images and make them available without needing to
use Windows Explorer.
(Turns out they were right. Most people don't
know how to use a file system like Exporer. Picasa
was a big hit.)

My impression is that this asset management software
has matured and can do things like finding EXIF data,
similar images, etc. I'm sorry I can't give you a link,
but that's all I know. If someone doesn't answer here
then try the photo group.
