Ok, I agree to these arguments. Les, Your company is providing a CAM application. Have You considered implementing Nurbs for all the splines and other nasty geometry, that cannot be described by arcs? LinuxCNC has support for Nurbs (but I guess that Mach users might be Your biggest audience and I guess that Mach is not even close to accepting Nurbs code).
