Anyways, the LOD works now. I haven't finished getting the cracks between the chunks perfectly flush, but should be able to get it done soon.
My test terrain uses 1,000,000 polygons, and usually only renders about 26,000. Adding layers will probably push that up to about 50,000 polys, which I think is totally acceptable. Oh, and I am testing with the largest terrain I think an FPS game would ever need. I haven't measured or anything, but it feels like about the size of a big UT onslaught map. So if a mostly-terrain map needs to render 50,000 polys per frame, a smaller map with more architecture should be okay, too.
I had to disable the layers while working out the LOD stuff. It looks pretty good:
