SimpleReach is a demonstration of the System Configuration framework asynchronous network reachability API, which lets you determine whether a particular host is reachable and monitor reachability changes. It's important that you understand that, when this API says that the host is reachable, it means that nothing on *this* computer will prevent you from connecting with the host. Factors that are external to this computer may still prevent you from connecting.
