From random points on the surface of an object, outward in the direction 
of the normal. The same, inward from the direction of the normal. From a 
point on a spline, forward or backward along the spline. With various 
distributions of jitter. Etc, etc, etc...

There's too many possibilities to do all the special cases, you'd be 
better off to parametize things like emission rate, origin, and 
direction.
