Google maps link buried in iPhoto

Bless those brave Mac folk, who I assume have lots of free time, that delve into the source of Apple's applications to see what they can see. A MacTelChat forum user took a spin around iPhoto and discovered that it can hold GPS data for images. This isn't anything new, granted, but when combined with the fact that they found both a reference to Google Maps and a hidden button labeled 'Show' in the info pane of a picture - let the rumors commence.

Could this signal the much speculated partnership between Google and Apple?
