EasyNetQ's proposed new send/receive API. This is for sending messages explicitly to a named destination queue via the default exchange. The Receive call creates a consumer for the specified message type. Further calls to Receive with the same queue, but a different message type will add additional message handlers to the same consumer.

IBus.cs

        /// <summary>
        /// Send a message directly to a queue
        /// </summary>
        /// <typeparam name="T">The type of message to send</typeparam>
        /// <param name="queue">The queue to send to</param>
        /// <param name="message">The message</param>
        void Send<T>(string queue, T message);

        /// <summary>
        /// Receive messages from a queue.
        /// Multiple calls to Receive for the same queue, but with different message types
        /// will add multiple message handlers to the same consumer.
        /// </summary>
        /// <typeparam name="T">The type of message to receive</typeparam>
        /// <param name="queue">The queue to receive from</param>
        /// <param name="onMessage">The message handler</param>
        void Receive<T>(string queue, Action<T> onMessage);

        /// <summary>
        /// Receive messages from a queue.
        /// Multiple calls to Receive for the same queue, but with different message types
        /// will add multiple message handlers to the same consumer.
        /// </summary>
        /// <typeparam name="T">The type of message to receive</typeparam>
        /// <param name="queue">The queue to receive from</param>
        /// <param name="onMessage">The asychronous message handler</param>
        void Receive<T>(string queue, Func<T, Task> onMessage);

That's fine, I think it's robust enough, and it can be a good enhancement. thanks!
