The ability to make arbitrary changes is essential for this.

Maybe there are multiple reasons for that.
One is that we're not in the business of trolling coworkers and losing time, quite the opposite. However I can understand that when I was little that would be fun sometimes.
Another reason is that we often use another channel to coordinate our work, email (I'll be working on that), chat or voice calls. The risk of undoing someone's work is nil.
With the approach of Airborn it could happen that I have to say "please move your cursor somewhere else so I can show you an alternative" or fix a typo. That would be odd and make us lose time.
The only scenario where I can see this being a bad decision would be for bots. For example, if you had a spell checker loaded which ran as a separate user rather than under your own session; so the spell checker couldn't auto-correct words until you'd finished typing the sentence. Here I'm imagining something like Rosie the translator bot from the original Google Wave demo... But I don't think you have bots anyway, so this won't be a concern for the present anyway.
