A space _is_ a geom. So you can use dGeomGetClass to get the geoms class 
number and if it is dSimpleSpaceClass or dHashSpaceClass you can cast it to a 
dSpaceID.

But dSpaceCollide2 collides spaces not geoms. You could give it the space that 
contains the ray and the other space. You can get the rays space with 
dGeomGetSpace.
