   Please forgive a very tiny picked nit, but I just want to be sure I'm not
   missing something subtle here:

You're correct to pick up on this point.

   When you say "the same flipping ink" does this imply that there can be more
   than one "flipping-ink"?  Is there something other than what's bound on

In theory, you can make a flipping ink (with CLIM:MAKE-FLIPPING-INK
natch :-) which will turn ink1 into ink2, and vice versa.  However
it's undefined what this ink will do to any (other) third ink.
