BSP Trees and sphere collision detection/response

I have recently been playing with bsp trees (new to the area). What is the best method to go about collision detection between bsp trees and bounding spheres? Seems like it would be a pain to break up the sphere in to fragments and push it through the bsp. Obviously there is a better way. Could you please let me know what it is? Thank you much.

Go to and read the tutorials. There are LOTS there.
