With regard to Bezier curves and circles, can anyone tell me whether it’s possible to create new control points from the exact intersection of two curves by just a click or two? (ideally while not affecting the curves).
Consider it this way, to give a simplified version of what I’m trying to do, how would one go about creating a big cloud shaped blob from a whole bunch of overlapping Bezier circles?
Curves are not very well developed in Blender and don’t interact with one another. You can try Meta(ball) objects or Dupliverted Spheres.

Thanks Fligh, thought as much
For complex shapes, perhaps you could first draw your curve on a 2d vector program like Inkscape, then import the svg path to Blender.
Another way would be to start with polygon meshes. Look for Geom Tool script. It can find edge intersections. Or you could perhaps do booleans to combine the shapes. Then select the outline and use the mesh to curve script to convert the edgeloop to curve.
