I have an interesting one. A client created a number of training videos for employees, and he wants a way to prevent the users from copying the files period . They are mp4 format files, so the users will need to play them, which my understanding via NTFS a read right includes copy. Might this be a job for AD RMS? Does installing it compromise or change the security on anything else on the box, that is, if it is a good choice, or can you simply point it to a/the training share?
Another option could be to leave the videos on external usb drives, if again there is a way to protect them from copying, but they are portable and therefore "could" disappear.
