There is a new release of MapCruncher...check it out... 

MapCruncher lets users quickly convert existing maps into an online format that’s as fast and easy to use as Virtual Earth. PDF and raster maps can be converted in minutes just by clicking on corresponding landmarks on the user's map and the global maps in Virtual Earth. MapCruncher re-projects the user's map, rendering correctly registered and zoomed tiles that can be mashed up seamlessly with Virtual Earth’s standard road and aerial imagery.
