I went ahead and wrote a prototype of this. It works by having Sweave output a \special that contains the information necessary to patch the .dvi file so it points to the .Rnw rather than .tex source. There's an R function that carries out the patching, after you run latex on the document. Currently the patching runs pretty slowly, but I suspect if I rewrite it in C rather than R it would be acceptably fast. If anyone has any interest in this, please let me know.
