Wouldn't it make sense for passengers to be required to enter their Drivers License or State ID or whatever ID they plan to use when booking the reservation? It would be a good idea to have either the Drivers License State ID and Passport ID# stored in the profile and the DHS would be able to see if you have a warrant or other suspicious circumstance and not clear you to fly.

One other idea is before you can print your boarding pass the DHS could have you fill out a survey answering questions like a "Pre-screen" survey that they do for job selection online. In return for answering psychological based questions you can be allowed to bring on liquids etc. Of course your background check is run at the time as well.
