Hi Terry, I've been wondering about archive functionality, in particular about the reading of file internal references such as reading the imagery referenced by a scene graph where both are stored in the same archive. The intent of the osgDB::Options support in ReaderWriter's is that nested references should by handled by prepending of the path to the parent file to a locally cloned osgDB::Options object that is then passed on when doing the readImage(..) etc call. I haven't done the testing yet to confirm the behaviour in the context of Archives yet but what in theory should be happening is that the archive should be added to the Options object on access to it, and suspect this isn't happening for all usage models.
Could it be that the problems you are seeing a related to this issue? I'm hopeful that if we sort out the proper prepending of the archive path to the Options object we won't need to intrusive changes to osgDB::Registry that you've had to make.
