Wow, this is a bold statement... do you deal at all with asymetrically routed customers? odd protocols? wierd applications? for any 'large' sized provider knowledge of the traffic beyond "its ip" is going to be a very difficult task. Even knowledge of address ranges crossing the network is a tough task give some customers default all traffic via one provider OUT and in through an alternate provider (assymetrical routing). Really, filtering anything but point incidents isn't a simple task, and at times point incidents are a challenge :)
