You'll likely be using the same code to find the nodes of interest no
matter what approach you use, to me it's really just an issue where it'll
be most convenient/flexible for you to invoke it in your application.

If you are loading the files directly by your application by calling
osgDB::readNodeFile(..) then adding post processing in afterwards would be
easy, but if the files are being read as part of paged database then using
the ReadFileCallback would be required.
