World Video Conferencing

One of my favorite television ad campaigns promotes Cisco System's TelePresence.
This one's my favorite: check out the video. Staring contests are great fun, but think of the possibilities for collaboration, exploration, and interactivity that are created by virtually connecting a classroom here in Commerce City with classrooms across the nation and the globe.
While I'm just beginning to learn about the TelePresence system, I know enough to realize I want something like it in our classrooms.
Is there any teacher who wouldn't like to offer students (let alone him/herself) a chance to build relationships spanning the globe? Now more than ever, we have the ability to equip our classrooms for collaborative learning and real-world problem solving.
