I don't think there is. Furthermore, I don't think there can be such a thing. By its very nature, DRM only works if the user is not in full control of the device, because at its core it denies the user (as opposed to the reader software) access to the decryption algorithm and/or key that is needed to access the DRM-infested material. Open Source DRM would make the decryption algorithm public as well as show exactly how to retrieve the decryption key, thereby making DRM pointless.
There
might be Open Source solutions for water-marking-style "soft" DRM, which does not restrict access but only makes it possible to track the origin of a file.
