Let's say you had the software that allows you to publish "protected" sound and video files. Wouldn't you be able to encode media in a way that requires you to manually authorize each viewing? I suppose the whole point of DRM is to be able to non-interactively allow playback from an authorized computer, but it would nice to hack that stack to require a manual intervention for the decryption to proceed. Having a DRM auth server on computer may be non-suspicious enough to avoid assumption of guilt for possession of encrypted secrets. If your computer were searched or seized, then you might get into trouble, explaining that the DRM-protected content was benign and not possible to re-authorize.

If they don't give you a blank stare, you might have a viable vendor. It's like a tech vendor selling to a hospital needs to know what HIPAA is.
