I think zman just uploads stuff to etree and others up it archive. I'm not sure. I'll check with him. He may upload them himself or have a person that does it for him. It requires no permission. Once it's out there, it's out there. What we don't need is multiple people trying to up the same source to archive.
ETA: I just added a comment on the torrent and will copy zman in a pm over on taperssection.com
