It would be helpful for the State Department to setup a process tracking website for the passport process. Something similar to how FedEx/UPS/USPS allow you to track packages and get email updates about their status. E.g. that application for renewal has been received, new passport has been send, etc. This is particularly important for US citzens living overseas who may need to use their passport on a regular basis and could experience serious problems if they need to travel or prove their identity while its being renewed.
