Well, very nice to hear that :), because I use a very similar technique to render nearly 2000 vertex colored and lit curvilinear tubes with the tube cross-section consisting of 12 segments. Each tube is modeled as an IndexedTriangleStripArray with the strips running along the entire length of the tube, though in principle the entire group of tubes can be put under one GeometryArray.
