Short answer, no.
Long answer, with a combination of material animation, careful key framing, props, transform controls, *morphs*, angles, and physics....(whew). Yes, you can achieve real time on screen clothing removal.
While this can enhance a scene, the amount of work involved in creating a detailed un-robing of an avatar isn't really worth the time it takes to get it perfect. Remember that film making is often about creating illusions (especially animation films) in the audiences minds. Often times the viewer will detail a scene through perception with very little visual data.
