With the DVD finally being released in a few months, I guess it's not really worth it to make the LD conversion public since the new DVD should look great (they've spent years tracking down the best film elements).

But the commentary is definitely worth preserving since it was the first ever recorded! Maybe if you don't want to go to the trouble of releasing an entire disc for a commentary, it might be more convenient to rip the commentary and maybe release it as an mp3 file or something. I know it's a track I'm very interested in listening to.
