LE'd runners who click on a teammate's belt actually unlock the belt for all players. I figured this out when a guy tried to get his belt back on an LE'd character and he unlocked the belt for us. The LE'd guy can't open the belt and there is no indication that it was opened for others.
Also, when I /set kill_self 1 and tried to loot the belt on another character it said I "did not have first access privileges."
