In terms of selling file pieces, if it’s too complex and trivializing to let people list individual pieces by themselves, how about letting people simultaneously list “all but one” of every piece of a file that’s partially completed (e.g. if I have 4x piece #1 and 3x piece #9 I would give up 3x piece #1 and 2x piece #9). Then list each individual piece blindly as “Piece of [name of .moar file].” So buying it/winning an auction for it wouldn’t really be any different than getting a forum to drop it. So it really wouldn’t make completing high quality .moars “trivial”.

It also would let people get rid of excess file pieces that just clog up inventory. I recently completed darkside, and after extracting it I had about 250 pieces of the file remaining. I never want to see HOFF again, so I’m not going to make any more copies. I’d just like to be rid of those 250 pieces; whether or not I get anything out of it.
