What about something with steganography? Most of the time they have to have a lot of encoding information for various file types but I was thinking of a way to have basically a "byte map" to enable it to work with all files.

Basically, say you have one rather large file and a smaller one that you want to "hide inside" the large file. Instead of actually splicing bytes into the large file, why not map each individual value that the file you want to hide has, to a corresponding byte with an equal value in the large file, and then just encrypt that file position. Then on the other end, there is no actual data hidden in the file, but rather a "map" more appropriately to extract the needed information.

The hard part of it would be implementing certain encryption standards. That and finding a way to make sure that the large file has enough entropy to actually map every byte of the smaller file; an iso file for example would have too many zeros, and more file positions would be used more frequently, potentially weakening encryption.

Just an idea I've been tossing around in my own head that I don't mind getting GPL'd. Fifteen other people have probably had it; and that's probably underestimating it.
