// Signs up self to receive KVO notifications about given properties
// on any new value and removes self as an observer from the old value.

// For example, to observe properties of a property called customer
// (backed by ivar _customer):
// PCPropertyObserver(customer, @"allowSubscriptionPurchase", @"availableProducts");

// You'd need to write this selector yourself:

Creating an awful Wi-Fi network

1. Plug an Ethernet cable into your computer. You'll need this for Internet connectivity while your Wi-Fi card is used to create a network.

2. Enable Internet Sharing in System Preferences.

3. Get your phone connected to the network you just created and make sure you can browse the web.

4. Ensure dummynet'd packets are still routed through the normal rules so masquerading works:

    eleos@Nebula ~$ sudo sysctl -w net.inet.ip.fw.one_pass=0
    net.inet.ip.fw.one_pass: 0 -> 0
