Digimarc Watermark Embedding

Does anyone use this service? Re devices it can be used with, all I can find on their website is descriptions of how it can be used with smartphones.
If somebody downloads my image onto a Mac, PC or Tablet, will the watermark be detected?
Also, can I search for the watermarks using my mac or PC as well as a smartphone?
What other service providers are good here?

Anyone any info here?
The only sample images I can come across are either for printed material or where the watermark is still quite obvious. I have looked for samples, incl. from Digimarc where the watermark is not obvious but can be picked up by my mac, but can't find any. Anyone know where I can get them?

Thanks guys,
I have an open mind on this one. A visible watermark communicates the images' ownership very clearly without any detection software being required by the viewer, but I reckon they often spoil the picture.
A hidden one allows traceability and (obviously) doesn't ruin the image. However, for Digimarc at least, the viewer would require Digimarc software or photo editing software to deteict it. Most people wouldn't have those.
Are their any more pros and cons to each system?
I'm even considering the possibility of using both, to make sure the ownership is easily communicated without software on their part, but also for it to be traceable.

Perhaps it's asking the impossible, but what I would really like is some notification that comes with the image directing the viewer to my site without them needing extra software. However, it can't be part of the image. Any ideas?

These would have to be detectable on all types of computer and smartphone. As far as I can see, Digimarc is for Smartphones.

That would be a billion dollar idea. If you solve that one, good times ahead....

There is nothing useful that would redirect the user if the image has been copied.
I put EXIF headers in my pictures (yes they could be removed), and a 1 pixel color change text watermark in each tile.
I haven't seen any arguments for anything that is better than this.

I was in touch with the Zoomify folks a while back, their focus at that time was a box you had to click to acknowledge copyright before viewing the image.
One panographer I recall imbedded a watermark in an inconspicuous place (not the nadir) so he could later say ... "see, you stole this"
Fundamentally you can't avoid theft, only detect it and launch legal action after the fact.

We had a thread a longer time ago, that multiple panos have been used by taking out visible copyright by for example limit up and down movements. So it stopped before you could see the copyright. After a longer discussion of those who saw their Panos on a website, the company took them off the website. I informed google as well about copyright problems with this website.
What do I like to say? I believe a digimarc helps you to control who is using your panos illegally. The thread showed several examples how people take off visible copyrights. So the digimarc for me is a safety add-on.
But right now there doesn't seem to be the Non-Plus Ultra to avoid theft.
