I was concerned because the OSG does lots of matrix and vector maths when doing the cull traversal, all of this uses either double or float types, and I how things all maps across when you have fixed point is an unknown to me. If it's not an issue and the compiler can compile double and float types albeit as fixed point internally then great.
