I just recently bought a Kryptonite New York Mini U-lock (it was $40 on amazon!) and have been trying to manage a way to mount it to my frame instead of putting it in my drawstring backpack. I still haven't found a way, but while searching I found this picture and was curious if anybody knew about this mount considering I've got that very lock !
Otherwise, to those that may have frame mounted NY minis, how do you do it?
