HI Andreas, As Serge suggested, it might just be far more productive to use the OSG's built in database paging support. All you need to do is decorate your subgraphs with a osg::PagedLOD or osg::ProxyNode, with osg::PagedLOD being the method of choice as it'll do load balancing for you - both loading new tiles on demand and deleting ones that are no longer required, all automatically done by osgDB::DatabasePager/osgViewer.
