I have a variety of data sources I'm trying to use together for the
purpose of understanding a neighborhood, including 400dpi 100 foot per
inch topographic maps, 1938 vintage aerial photos, modern aerial photos,
and a plant map updated to 1983. Only the modern aerial photos are
georeferenced.
Try the MetaCarta Labs Rectifier, perhaps?

Well, one problem it has is no way to input known coordinates for a point.
I have to match it to another map (at least one Pittsburgh map is there)
Likewise, the distortion on the PennPilot aerials (one is there) makes
that fun also, but not impossible. I have obviously played with it.
One piece, the plant map, for copyright reasons I can't upload. I don't
(yet) have the owner of the document's permission to distribute.
