Hi Robert,
The solution you had presented me with a few weeks back has been
working out great for me. I just thought that if this is an often
requested feature then OSG might benefit from having the code built
right in... I'm still very new to OSG, so was just wondering if that
addition would be worth while or not.

Might it make sense to add an optional callback to either the
PagedLOD+ProxyNode classes or to the DatabasePager for when loading of a
node is complete? If so, would patches be accepted?
The osgDB::ReadFileCallback allows you to report when a subgraph is loaded
by allowing you to call the standard osgDB::Registry::readFile(..) and then
process the subgraph, do any optional signally you want and return the
processed subgraph.
However, if you actually want to take charge of when the subgraph is
actually merged then there isn't presently a callback from it but you can
subclass from osgDB::DatabasePager and override the
DartabasePager::updateSceneGraph() method there merged loaded subgraphs
with the main scene graph.
Robert.
