BF: I highly doubt the film curvature will change while in the scanner.

BF: With NikonScan 3.1 on the Mac I can set a focus point anywhere on 
the image and it truly seems to be a POINT not a LINE. To verify this 
behavior set the focus point anywhere on the image and read the focus 
value readout.  Then set the focus point at various places along a 
vertical line running through the original point; you'll see that the 
focus value changes.  The same holds occurs in the horizontal 
direction.
