Ok, how have I never known about Jing? That is awesome! I think Jing would be a great way to create tutorial videos for students. Students could even create their own "how to" videos for their classmates, so we would have a class tutorial bank.
I think that the use of Skype could open up the possibilites of working with classes all over the world. I have seen online service projects with schools from not only different states but different countries working together in all of the core content areas. I think the possibilities for WAIS to move in the direction of working with classes from different parts of the world is incredibly exciting.
