i'm pretty sure chris colfax's spline animator macro does all this.  the
camera (or any object) follows a defined spline, turning, and banking. 
in fact he has controls so you can adjust the amount of banking.  and i
think it is just a pov file so you should be able to read whatever
information you need from it.
