Postcard mailing system for virtual tour providers using krpano

Hello VRtists
Northstudio360 has just finished its first draft of a postcard mailing system that allows the viewer to frame up a picture from within the 360 tour, take a picture, add a stamp and mail that image to a friend. This will attract others to view the tour and add another level of interactivity for viewers. Im hoping to package this so that other tour providers using the krpano player will be able to implement this feature easily. It still needs to be skinned but the basic functionality is there. I would love to hear any ideas on how we might be able to make this feature better.
