Serious question: how often do you approach the publisher and ask for their help with this? Have you developed an administrative system that could present these requests in a standardized and actionable way to the publishers' legal departments, or just the technical system?
As far as help goes, we actually don't need technical help. (I won't expand on this, of course.) It is mostly a matter of getting permission. As far as an administrative system for asking, there isn't such a system. My understanding is that permission comes most reliably through personal contacts with company insiders. Asking legal departments is usually counterproductive -- after all, if you worked in a legal department, what motivation would there be for you to say anything but "no?" Saying "yes" has all the possible downsides and no apparent upside.
