That would be nice. The intial versions were already awesome and i would 
really like to play around with it even more.

I'm wondering if it would be useful to create the intersection 
meshes/curves on the fly if the bounding box for a segment is it. This 
is obviously slower, but it could save a lot of memory. I guess the CPU 
implementation does this already for curved segments. Right?
