Rich tried this and I futzed with it a little bit; we tried using encode/decode filters - but I believe it would slow down pulls/clones incredibly as it would have to transform each and every single file on a pull/clone/push. I think Rich expressed this same concern. I didn't do any formal timings though... Rich?
