Really, this doesn't need to be very complicated at all.
You need eleven bit-by-bit identical disks. One of these disks is designated (and identified) as the control and is guaranteed to not have been treated.
The other ten are either treated or not treated by a coin toss, and recorded by paper in a sealed envelope and continuous video tape.
It's okay if a rep for the applicant is present, so long as this rep does not touch the equipment nor the coin, nor contacts the applicant in any way between that point and the time of the test. If any of these things happen, the test is invalidated.
The treatment machine is borrowed/provided by JREF, set once prior to the initial treatment, and not adjusted until the treatment is done.
This is done entirely out of sight of the applicant.
Once this is done, all "treaters" leave the area. One neutral, who was not present for the treatment, enters and transports the CDs to the room where the applicant awaits with their preferred equipment setup. (This can include packaging and mailing, in terms of a remote test.)
The applicant then receives all eleven CDs, and determines by any means they desire which CDs have been treated and which have not.
The applicant can handle the disks, or not handle the disks as he/she desires. The applicant may tweak the equipment at any point during the test. They may do bitwise comparisons, or as many listens as they like. They may switch CDs at will. The applicant can eat the disks if that is what it takes for them to tell the difference.
The applicant provides whatever equipment and environment they feel they require to make the determination, subject to inspection for communication vectors (smuggled cell phones, etc.)
