Not something I need currently but it sure looks promising and absolutely something I’ll revisit when (not if) the need arises.
Well done! 
I am using Ace in a test app.
So far it works very well. A simple 2 player turn based game. The screen casts are clear and most helpful. And I really like the idea that the server code is ‘lua’.
Thanks Dev!
