One point of stealth-pgp is to make an encrypted message you _can_ safely hide with stego. Since the Bad Guys can take your stegofied picture, destego it, and see the string ------ BEGIN PGP CONTRABAND DATA, you can't get away with saying "no, that's just a picture of my cat, blurred a bit because he was moving", which you can if you use a true stealth version of PGP or other crypto program.
Or, you can develop a public-key stego system... ie a stego system that uses bits in specific ways depending on the private key of the recipient. Something I've been thinking about, but haven't quite figured out how to do yet, except that one could use certain bits based on a PRNG and begin the message with an RSA-encrypted seed (ie the first X bits will be the seed, encrypted with your public PGP key). (If anyone actually wants to code this, lemme know...)
