I've already talked with Don and his refactoring wasn't really related to this part of mongo. He redid the entire xmodule modulestore and whatnot, but it didn't include how we do static files.

When I talked to be the impression I got was that we were going to try to stop even putting the transcripts here since it doesn't really make sense. 

Additionally, right now this is the only defining characteristic of those files. I think that any attempt to make this more constrained would miss a non-negligible portion of transcripts.
