I remembering reading up on this a long time ago, did a little sudying on it.... I don't know how usefull as a water mark it would be... I think it can be used as a good tracking as long as they don't change the format..
I have the impression, I can be easily wrong, that if they change the format let say from jpg to tif that erases that info..
I did a quickie look around..... I found this link that had several programs listed.... http://www.tech-faq.com/steganography.shtml

I'm thinking it might be good for watermarking copyright info on photos.
