NServiceBus message interception?

Question

Is there any way to intercept messages in NServiceBus?

From now i can do it manually via introducing base message handler like this:

public abstract class MessageHandler<T> : IHandleMessages<T>
    where T : IMessage
{
    public IBus Bus { get; set; }

    protected abstract void HandleCommand(T command);

    public void Handle(T command)
    {
        // perform some logic on *command* before
        HandleCommand(command);
        // perform some logic on *command* after
    }
}

And the usage:

public class ConcreteMessageHandler : MessageHandler<ConcreteMessage>
{
    protected override void HandleCommand(ConcreteMessage message)
    {
        //handle command
    }
}

But doing this way i'm loosing an ability to subscribe to multiple messages (because i cannot inherit from multiple MessageHandler<> classes).

Take a look at the message module feature http://jonathan-oliver.blogspot.com/2010/04/nservicebus-message-modules.html
