Can movie data from a movie strip in the VSE link to data in a texture? In one scene of my .blend file, I use a frame from a video file in a texture. In another scene, I have a movie strip in the VSE that uses the same video file. Since this is Blender, I assumed that I would be able to link the data for the movie strip from the data for the movie into the texture, but I cannot see a way to do this.  

What I really need is for one to be changed when the other is. Right now my solution is a really ugly python function, but I'd rather it work like other objects/strips in Blender. Is there a way to link the data used in strips in the VSE from other parts of Blender?
Make a scene that renders or outputs the texture (eg. connect it to a composite output). Then in the sequencer instead of adding the video select the scene strip from the Shift+A (Add) menu.
