@Prestidigitationer: Look into some of the Tiger Claw maneuvers for swordsage. Several of those provide a similar ability.
Sudden Leap allows you to make a jump check as a swift action and then a full attack at L1. At L5 Pouncing Charge lets you make a full attack after a charge at with your full attack bonus for EACH attack...
Barring that I'd also be willing to let you use the "Catfolks Pounce" feat even though it's normally only for catfolk.
It allows you to execute the pounce attack on flat footed opponents.
