Well, you are better at this math than I am...you can of course rotate
vectors around axis, (vaxis_rotate) also, if you know the length of a
vector (I believe there is a function for that) you could of course just
create a vector <L,0,0> where L is the length of the vector, and x is
the axis you want it along.  Otherwise, finding the angle between the
axis isn't too hard, just some simple trig involving the length of the
vector, and the component you want to lose (ie if you want it along the
xy plane, it would be asin(z/L)... I don't know exactly what you want,
but perhaps that helps?
