    As andreas said, i would suggest keeping the server simple and
    background-only. Configuration can happen via file or privileged users.

    Sounds like a classic scenario for a Singleton to me. The Singleton would
    serve as a "connection registry" to which each connection adds itself on
    creation, and updates itself whenever something significant happens. Just
    be sure to unregister each connection once it dies. (the finally statement
    can be very helpful for such cleanup duties!)
