For those interested in steganography-based encryption techniques, some well-known cryptology researchers designed a system for formally transforming encrypted messages into the (well-formed) contents of arbitrary protocols or communication mediums. The technique is called format transforming encryption [1], and it could be applicable here to help conceal the very presence of encryption being used by one who knows the stegonagraphic scheme.
