I've heard of this before but can't find that same article right now. The
idea I remember made a number of keyed transformations on sets of symbols
that could compress low entropy density plaintext. Might have the pdf
around somewhere... Meanwhile, other articles Google returned:

Otherwise, one could mix streaming compression with streaming ciphers and
feed the output of one right to the other without touching disk in between.
