You are talking about steganography.

1ilzolende5yI know that sixes_and_sevens probably wants a software solution here, but if they are willing to put up with sending lots of extra data they could just declare the third letter of every sixth word or use some other similarly arbitrary rule to determine which letters were pieces of data in the secret message. There's also lots of tools to steganographically embed data in images.
