I know this is an old thread, but did anything ever come of this? It would still be useful to have something like UIStick. I'm trying to do the same thing as jz87 wanted to do - build a dialog box from a UISlicedSprite (scaled by a UIStretch to take up a specific proportion of the screen regardless of resolution and aspect ration), and then arrange the text, buttons and other elements relative to that UISlicedSprite.
