If you could split the group in two, you could create an 'A' key and a
'B' key, double-encrypt the secret documents with both, then
distribute the 'A' key to each member of the 'A' group, and similarly
give the 'B' group copies of the 'B' key. This means whoever's
producing the documents only needs to encrypt twice, but it does mean
that if the 'A' group are wiped out, the 'B' group cannot access the
blueprints to the doomsday device (or whatever).
