Say Person A and Person B are working on a slide that has the text "Hello World" centered on a white background.
Person A makes a change to the slide by changing the background to red and moving the text box up 10 pixels.
Person B makes a change to the slide by changing the text to "Hello World!"
They both sync at the same time.
Ideally, Kivo would be able to differentiate the changes as non-conflicting. For some reason I doubt Microsoft's Powerpoint API allows you to differentiate between those changes, however. :)
