Seen an approach to this that relied on transcribing existing text and
choosing synonyms for the words such that the original meaning was
preserved; downside was it was a really low bandwidth channel, with only
a couple of bits per altered word and not every word capable of being
altered in a sentence without completely changing the meaning.
