Sounds very similar to Hitch[0] which launched a couple of months ago in SF. It sounds very useful for long, expensive trips (e.g., cross bay, down to south bay) where the fixed cost of picking up or dropping off another passenger is a smaller factor.
On an unrelated note, how is the form at the bottom supposed to update you when UberPool is in your area? Area codes are going to be inaccurate for anybody who's moved since they got their cell phone number.
