I got through gate security just fine. Next time I know that flying without ID is called flying "selectee". I can simply go to the agent and the ticket counter and tell them I am flying selectee and I'm good to go. As an aside, since the TSA takes you aside and searches your carryons and such they take you right to the front. On a busy day, that has to be faster than actually flying regular! I was almost through faster than my coworker, and it was a pretty short line!
