Hey Eric! I won't forget our brainstorming session. Multiplayer covers the needs of repl cast, and man oh man we went through so many iterations!
I hope you like it and I hope it's helpful to you and to the people you teach. Let us know if you have feedback or ideas, I would love to hear them.
Hard to believe 7 months have already gone by since I was working with you on this prototype! I took a peek at some of the websocket messages, and I'm glad to see its come a long way since I last saw it :-D
This launch seems to perfectly cover the vision of collaborative coding that the repl.it community has been clamoring for!
