lwjgl does not support nurbs. The reason for this, I'm told, is because of some callback work thats apparently tricky to get right. Having done some callback work in fmod, I know it's doable - but I don't know all the details. Just that Jogl doesn't have it either, for the same reasons.
I know Darkprophet has been working on GLU in general, and he did talk about tackling nurbs later on, but I don't know the status of this.
