There used to be hacks like that for the PC years ago, that would let you create a self-displaying text file. the user didn't have to have anything installed to read it -- all they had to do was run the program.
there are still programs like that available on PC's but the fear of trojan viruses has pretty much done them in I think. Most of the companies doing this now allow a separate format for the book itself. These items are in the wiki.
