Right, and there are a couple of possibly reasonable ways to rotate the
workpiece.  Are you thinking of rotating the workpiece around its long
axis?  I don't think this is equivalent to a ramped shooting board.
Imagine shooting a miter on a picture frame molding.  Rotating the
molding about its long axis will change the orientation of the miter on
the end of the board (think of going from "flat" frame to a "shadow box"
frame), but a ramped shooting board doesn't have this effect.  And I
think that rotating the workpiece about its long axis doesn't affect the
cutting mechanics.  Imagine shooting a miter on the end of a dowel -
rotating the dowel doesn't change how the blade cuts the wood fibers.
