Live co-editing (beta) Is this Email a Scam or Real from Adobe?

Dave, Jane and myself assessed this before it went live, and were very impressed.  We could all see what the others were doing, what layers were selected etc.  This was a while back, and my memory is fading a bit, but I think we were able to undo our own edits, but not other people's.  I am not 100% on that.   We thought it could be an excellent teaching aid either one-on-one, or with a remote class full, as well as a way for content creators to interact with clients and their art directors.  It might need some control, like the ability for the initial sharer to lock layers.  But it was fast and flawless, and the three of us could not have been further away from each other without leaving the planet.  I am sure people will think of interesting ways to use this going forward.  

We used Adobe Connect to communicate with each other, but this is separate from the co-edit, so you could use whatever works for you.  An excellent tool just waiting for people to discover and realise how useful it could be.
