Not nit-picking at all. It's hard to help someone with their issue without having any sense of what their involvement is and where they're coming from or what their market actually is. The reality is that to have a decent chance of suggesting a useful direction, we need to have a sense for this market we're being told exists. Are they a small group of highly interconnected people? People scattered over the globe with no connections to each other? A single group of student in a single university? Something else? Social watermarking isn't going to stop a family or a small business or a tight friends group sharing within their walls, for example, but it might lower the chances of a student offering a book on a shared bulletin board or a professional uploading it to a torrent site. If members of the target group are scattered and have no connections with others in the same group, I wouldn't see the point of DRM at all (well, I can't see the point of it anyway, but if I was a DRM fan I wouldn't see the point of it under those circumstances).
And the fact is that this particular example has been given makes me think that this market doesn't exist at all, since it's so wildly improbable, and makes me wonder whether this is all a hand-waving business startup idea, not a real thing that exists in the world -- so why should I grant the premise without any further questions?
