There really is a C++/programming question, rather than an OSG one. How do I pass data to a callback? OO hundrends of ways, which is the best oooo I don't know it all depends exactly on your app. Do you search for the node? Do you store the node pointer in the callback? Do you have a global pointer?

You need to work out how you relate two objects to each other. It's exactly the same issue as above. Main things to worry about is keeping the different implementation loosely coupled and avoid any circular references and dangling pointers in your implementation. This really is a C++/programming issue.
