It is time we smack all of you idiot melee lockdowns!

Dragon Magazine 350 has the feat "Ranged Threat"
Requires BAB +6, PBS, Precise Shot, and Combat Reflexes.
Gives you a 15' Threat range for ranged weapons. Why is that yummy? Because Stand Still does not specify Melee, only they have to provoke an AoO in a square that you threaten.
Thus, you can use a bow to Stand Still opponents, and hit loads of them. Of course, you could do this with a spiked chain at a slightly smaller range but *Shrugs!*
