Loading GIF files as MovieClips

For this flash application I’m building, it would be nice to have people upload their custom graphics and animations so my application can load them in run-time.
Is it possible to load a GIF file as a MovieClip that contains all frames in that GIF file? I want this to be as dynamic as possible, like the user tells my application the URL to a XML file that has all information about the graphics he wants to use, so that my application can download those graphics.
