OK - so it is just like the captain and the XO on the submarine. The famous
Niall O Broin instant analysis (TM, Copyright) indicates that what is
needed here is not multiple keys, but multiple passphrases i.e. when a key
is generated not just one passphrase is asked for, but an option to enter n
passphrases and an m, which is the number of passphrases required to decode.
There you go - a requirements spec. in a couple of lines. Functional specs.,
coding, testing etc. are left as exercises for the reader :-)
