TL;DR - Yes Long version - I have worked extensively with Digital Rights Management systems including Microsoft's own AD-RMS (which is a classic MS software - Overly Complex Architecture but Pretty Neat Features). Parts of what you are asking for is practical at all or impossible to implement. There are lots of factors when it comes down to protecting a document. Offline scenarios are real pain in the neck. Identifying the document/user/device/location is one of the challenges as well. There are many issues you see when you start a feasibility analysis on a requested feature and you have a bunch of them. In any of the cases, you need to bring your expectations down.
