Several people have attacked my original message because I dared to
question if we can protect information rendered in digital form.

The information may be text, audio, video, or images. Indeed, it
might be a hologram. After pointing out quite clearly that you cannot
do this, I suggested that we can make it inconvenient for people who
want to duplicate this information. But since it is not possible to
truly stop people from duplicating information, I then asked what
efforts exist to "watermark" information such that we can know who is
the offending distributor.

Now, I want to be clear. I am not interested in generating discussion
about how business should be conducted. Nor am I passing value
judgements on any particular stance. While I think we must be open to
looking at all facets of the problem, I am really only interested in
the technical discussion that pertains to marking data. So, please
accept that I will not reply to messages that attempt to engage me in
some sort of philosophical debate of what is right and what is wrong.
