There is no mechanism in any of the OSG libraries or plugins for implement DRM. However, the OSG ReaderWriter do support reading data from a istream, and you can implement any reading mechanism you want, such as read a file into memory, decypt it then pass this plugins for loading. The curl and gz plugins both use this approach albeit reading for http or uncompressing a file into memory, so you could look at these to see how they do it. The other approach would be to no trying a make an unreadable file, but make the scene graph data in it usable without processing. For instance you could take all the vertex arrays and imagery pre-process them so that they are encrypted, and then save this model out to disk, then on load you post process the scene graph to decrypt the data.
