These all are pretty cool, but all seem to work based on knowing the
current location, which is is the unknown in Michael's hypothetical
problem. But that said some of the tech behind these tools might be
useful in comparing photo to a potential reference image.
This is a very interesting and intriguing problem.

Consider the following hypothetical problem:
Assume we have a good elevation data set for a large region of
the earth -- say, an entire mountain range. Now let's say we
have a photograph taken from the ground, the horizon of which
shows the profile of a couple of the mountains in that range.
Can you tell me where the photograph was taken from?
Any pointers to research in this area would be appreciated.
I think that http://www.heywhatsthat.com/ does some of what you
want. I'm on a very slow hotel internet connection so I can't
actually get it to load just now. But my Delicious tags seem to
indicate it's an answer.
Yes, that is the one I have been thinking of since the start of this
thread. Thanks Ian, for suggesting heywhatsthat.com. It was pointed
out either on this list or on geowanking a long time ago, and I just
couldn't remember it. It is pretty cool.
