A historical Street View

Google Street View is an idea I liked. But it shows the street as of today. Is there a possibility to show a history of a street with a slider so that we can see how a street has changed over the years? Yes, I agree that Google is finding it tough even now to get images of all streets, but is this possible for those streets which have sufficient number of images already? Can this be recreated with appropriate software from old images that are available online from different users (say in Google Images, flickr, picasa, facebook etc)?
