There's new (?) sample for Google Earth API that looks very interesting:
"Earth Pad is an App Engine app that allows multiple users to collaboratively browse the globe. Earth Pad allows multiple users to share the same Earth viewing experience; when one user changes the view, it updates for the others. Users can create placemarks, which can then be seen by all the other users in the session, and even chat."

I didn't try it, but I love the idea. There're so many potential uses... |
