Overriding UIPasteboard Globally for iOS/iPhone

Question

The purpose of my application is to extend the functionality of the UIPasteboard across all applications on the iPhone. So if you are composing a text message, you could doubletap and access the extended UIPasteboard functionality. The same goes for email, Twitter, or any other occasion where a text field is present.

I don't really need an example or explanation of how to extend the UIPasteboard, I can figure that part out. The part I'm unsure of is creating a background application that can intercept events from other applications. I've never built one that was meant to sit around until someone performed a certain action in another application.

Any ideas or pointers? Thanks!

Not possible on a non-jailbroken device, I'm afraid. iOS apps are tightly sandboxed, for security and UX reasons—third-party software doesn’t get to mess with system-wide functionality.
