( It might be discussed before. )
Since C2 could create multi-players game by using multiplayer/websocket plugin, it also could be used to create a host/server -- it is just another special client.
It might be possible to deploy this exported client on node.js server (not node-webkit exported), by pure javascript code without any html element. Other logical things like collision, plugins, behaviors would be the same as normal html5 export.
