The camera controller in Awaybuilder tries to solve the rotate the shortest way problem when animating the camera. I'm not 100% sure it applies to what you are trying to do but the problem seems very similar. However, it uses rotationX, Y and Z instead of pan and tilt.
You can find it in the "navigateTo" method of "awaybuilder/camera/ CameraController.as"

Basically, I'm using a hover camera that moves around an object when the user click and drags. There are also buttons to move the camera to a certain side of the object. If the user pans or tilts the camera 1000's of degrees and then clicks a button to go to a side, the camera has to move around the object many revolutions before reaching the correct face. This is more of an actionscript question than related to a3d, but just hoping someone might have encountered this problem before and has advice. Thanks. Derek
