Chat feature

[varyndev]

A chat service is a key component of the system. The requirements are:

• real-time messaging many-to-many ad-hoc "rooms"
• a room is a collection of users who opt in
• rooms can be based on ad-hoc collection of users, members of a conference, or a group
• users join or leave a room
• message is broadcast to all members of the room
• users can participate in as many rooms simultaneously as they wish (maybe there is a limit but it should be high)
• users must be logged in and validated
• chat is secure, no man-in-the-middle eavesdropping or monitoring. only intended users can see activity
• chat history is maintained for a specified period of time, -1 infinite, 0 no history
• rooms have moderators to control blacklist, whitelist, block, etc.
• all API based such that different clients can be built.
