Can Scratch do multi-user game ?

In a multi-user game settings, typically each user has its own local state and exchange messages to update its own state.  I am not aware how these can be achieved in Scratch.  Or anyone can share their tricks ?

The current programming model in powerful enough that a slight extension to a "space" scope should be sufficient to incorporate this capability.

1. On top of "variable of this sprite" and "variable of all sprites", we add a scope: "variable of all sprites in this space".
2. When broadcast a message, we add an option to broadcast to all sprites within the space.

The communication among different players VM can happen via P2P or via a hosted message broker

Does it make sense ?  Thoughts ?
