Is this a personal project or something for JackBe (I notice you work there). Be mindful that many have tried to build this kind of system and there are a lot of pitfuls outside of just the technology - such as explicit ranking versis implicit/gestures (although I notice you are a UX designer, so you may be thinking of interface issues already). I've got some experience in this area if you are interesting in connecting - my email is in my profile.
