The new Secure Flight Program has begun with U.S. domestic flights and will cover international flights into, over, and from the U.S. later in Phase II. It should not affect Camino travel yet, but you can never tell what power-drunk security personnel will do! You can regularly find Americans treated the same way that the U.S. treats visitors from other countries regardless of the actual "rules." What goes around, comes around.
More from the TSA website:
Q. The name printed on my boarding is different than what appears on my government ID, will I still be able to fly?
A. Boarding passes may not always display the exact name you provided when booking your travel. The name you provide is used to perform the watch list matching before a boarding pass is ever issued, so small differences should not impact your travel. Secure Flight is a behind-the-scenes process that TSA and airlines collaborate on to compare the information you provide against government watch lists. The additional data elements that you may be asked to provide, such as date of birth and gender, serve to better differentiate you from individuals on the government watch list.
Q. What if my name and I.D. do not exactly match when I arrive at security? Will I be turned away and unable to fly?
A. No. Secure Flight will not impact the process at the security checkpoint in any way. At the security checkpoint, TSA strives to ensure you are who you say you are. TSA performs travel document checking to see that you, your identification, and your boarding pass match and are valid. TSA performs this function because identity matters and it is critical to security to ensure that individuals with hostile intent do not board aircraft.

Secure Flight will not impact the security checkpoint experience. While Secure Flight and travel document checking are both critical security functions, they serve different purposes at different points in the security process.
