Would this involve a razor blade and scotch tape, like I used to use in
splicing reel-to-reels?

Oh... I guess the idea is that you transfer from tape 1 to tape 2, then
destroy (or at least sequester) tape 1 that reveals sequence. Of
course, the out-of-order tape transfer introduces another failure
point: are we sure it won't skip some vote in the transfer and/or
transfer some other vote twice?

I don't know a way of doing that without preserving order. Can you
write to an arbitrary sector on an non-finalized CD-R? If that's
possible, it might make certain things easier for OVC's EVMix, since we
have some similar issues with the CD session used for EBIs.

I don't *like* Selker's sound recording scheme for verification. But I
think the narrow technical issue of recording ordering can probably be
handled procedurally. And Charlie likes to point out (accurately) that
many guarantees must be procedural, not wholly technical.
