wow, sounds fancy

I saw this previously, but I'm not sure how much it would help with anything besides an editorial image.  In other words, once you edit your image, I'm sure that the watermark/registration mark is gone.

But I'm sure it stays on the RAW files.  Definitely would be the best way yet devised to prove ownership of a RAW file for copyright infringement cases.  If they could set it up that it would be stripped from the RAW if it was edited by a program other than a few approved ones (Like Canon's, ACR) that cannot edit content (WB, Saturation, etc.. is not content, can't clone stamp in a RAW editor), it would be quite a big deal for the news industry, especially after the debacle at one of the major newpapers/magazines (can't remember where) somewhat recently that ran a Pulitzer class photo that was an edited combo of 2 photos, a huge no-no.
