I want to use OpenFeint in a MonoTouch project. I have no experience in creating the proper bindings to use a third party Objective-C library with Mono. Reading [this](http://docs.xamarin.com/ios/advanced_topics/binding_objective-c_types) article on the Xamarin website did not really help me any further. Has anyone created the bindings necessary to use OpenFeint with MonoTouch or has anyone experience with creating the bindings I need?
