J-S is right. If you're developing a Node that requires special handling 
during the cull traversal, writing a custom CullVisitor is overkill. You 
should just override traverse() in your custom node. If you ever submit 
your node for inclusion in OSG, you can migrate the cull handling code 
into osgUtil::CullVisitor at the time you make the submission. This is 
what I did when I developed OcclusionQueryNode.
