That's it :-).

For software T&L you can sort your verts (this is not necessarily specific
to VIPM btw.), so that verts [0...n] represent the first (lowest) lod level,
verts [0...n+m] represents the next lod level and so forth. Using the
dwStartVertex and dwNumVertices parameters in the DIPVB call you can
instruct DX to transform *only*  those verts that fall in the specified
range.
