Thanks for the answer. I agree with what you are saying but I think my question is as follows. Assuming I needed 1:1 to fill the frame on film with a specific subject I would obviously need to back off a bit and a lower magnification to fill the frame on digital with the same subject. I would now be working at less than life size would I not? Is this difference also a
factor of 1.5 like on telephoto?

Yes. :-)

Is it not also true that if you make an 8x10 from the film 1:1, and an 8x10 from the digital image, they will both show full size images, or full "frame" and be essentially the same?

Or are we going to throw the resolution of the negative vs the resolution of the sensor into the equation?

(I know that optically the image thrown on the sensor will be smaller [x.667] than the image on the film)
