Hmmmm... might be the only way to do it right now, but I'm thinking more along the lines of working in ProTools or Avid, where you can use the plugins to effect a sequence or selection, and then save the original media along with the METADATA instruction set. This would eliminate the "double media" dilemma, but unfortunately, we're not talking about freeware tools.

Alternatively, you could torrent an A/B example, and attach a poll for starters as to which (or both) version(s) should be fully distro'ed.

I have high confidence in your seeds, but I'm kind of speaking about the idea in general, and how it would apply across the board.
