Alternately you could look at some sort of secret sharing implementation where you encrypt and split up the master list into n chunks that you need any m of them to recover the original master list. Everyone gets a chunk of the list with their assignment and you'd have to have m of them collude to get it back (so you'd want to set m sufficiently high, of course).

(Well, you did say you were over-engineering . . . :)
