Devices like the CD-Rom with their large data capacity might be used
to hold substantial quantities of non-algorithmically derived data
which could be used in as a super-encryption based on a key driven
selection algorithm to conceal the mathematical regularities of an
underlying algorithmic transformation.

Even without applying transpositions we have >10**8 encryption
sequences in hand. It could complicate things a bit.

Another possibility is to use a large part of this capacity to hold
parametrized forms of, say, 10**5 distinct encryption algorithms
whose selection could be key driven along with 10**8 bytes of the
above data.
