HN's Daeken will expose security flaw in 4m hotel room keycard locks
I'm planning on doing a Reddit AMA for reversing in general -- as well as this work -- in the next hour or two, but if anyone has any questions I'll do my best to answer here.  All I ask is no protocol details (paper and full code will be out tomorrow immediately following my talk) and no legal questions.  Go wild.Edit: Since this thread has blown up a bit, we may as well just do it here for real.  If you have any reversing questions or background questions or whatnot, feel free.
