HI Christian, osgUtil::Optimizer has a visitor called StateVisitor that looks for duplicate state a removes it, by default it's called when you call Optimizer::optimize(..); The Optimizer will however only work on the scene graph you give it, so you have to give it the root node and is typically used at start up on the main scene graph.
For scene graphs that incremental add new subgraphs there is the osgDB::SharedStateManager that you can osgDB::Registry and have it do the merge for you. Robert.
