Is there a limit to the number of rooms you can create? I'm interested in building an app that lets users have private chat rooms so I assume I need one room per private chat. Can I create a room per user or should I create and delete them on the fly as needed (through a template)?
You might be able to achieve additional "private chats" through the use of multiple chat collections in a single room, which your app could spawn with specific user permissions on them to ensure privacy (product gurus care to comment???).
More or less the same result as having multiple rooms, but if you ever wanted to share chat context across other users, this would provide a potential path.
