Live Share is very cool. It's a different approach compared to the Cloud IDE "code on the server" approach that others have taken. I like that I don't need to interact with a web app or IDE in the browser and can share code directly between VSCode and Visual Studio.
I'm still wondering what kind of paid plans Microsoft might bring out. Since LiveShare has been released can I get excited knowing that at least what is out now will continue to be free in the future? Their FAQ says they are still evaluating options.
