The concept in some words
ZooDiscovery implements both ECF discovery interfaces: IDiscoveryAdvertiser and IDiscoveryLocator. That is, ZooDiscovery can publish our services and gets us noticed about discovered services. Perfect! But how? A ZooDiscovery instance running at your machine does its job by exchanging data with other ZooDiscovery instance(s) running elsewhere. So each running ZooDiscovety service must know where that other "elsewhere" exactly is. This is why we should first make our ZooDiscovery happy, giving it an IP address to play with. To keep it smooth, let's take it step by step following these cases:
