Hi Bruce, Take a look at osgEarth (http://www.osgearth.org) and see if it can help you out. osgEarth can composite multiple layers at runtime, so there is no need to create a low-res base database and high-res inset databases. This also allows you to add/remove layers from your scene quite easily by just editing a simple XML file or changing the layers through the API.
Let me know if you have any questions and I'll be glad to help you out. Thanks!
