-Controlling my Nexstar Evolution 8 with Skysafari as I already do sometimes
-I see an object and as I go to the information regarding the object I can see who else might be observing the same object at the same time
-Build a chat function or Google Hangouts possibly with a red enabled night vision camera for video chat
-Message board to include notes observers have on an object
Some collaboration opportunities would really be interesting. At minimum maybe a message board on each object allowing people to enter observing notes that are visible to all?
