Most of the time only one cull callback will be attached to nodes so it's safe just to use setCullCallback, especially as we're talking about an example that loads a database only composed on nodes and cullbacks that the core OSG will be adding. > I think what you suggest is reasonable.

Agghg.. ;-) Try the cull callback and see how you're getting on, even without using a cull callback there is likely other routes we can use to achieve what you are looking for.
