   One should not presume that they're necessarily always the same.  My
preferred highlight rendition would be a bold style.  Particularly in an
emacstool window with more than one emacs window, where the mode-lines
that separate them are rendered in inverse-video.  Some terminals are
capable of more than one style of highlighting (SGR escape sequence,
accessible from TERMINFO or TERMCAP).  If a desired highlight treatment
(set in .emacs) is unavailable for a given display, the default could be
to use the basic standout mode.  Emacstool (on Sun's) should consult
~/.defaults for the user's /Tty/Bold_style preferrence. 

   Ashwin Ram's thoughtful comments about WHEN to highlight the region
are well taken.  Such a feature would be WONDERFUL! When selecting a
region, I frequently bounce the cursor around with `C-x C-x' to help
visualize the selection.  Unnecessary if it's highlighted and the
highlight is cleared after processing the region with a command. 

   Two occasions when I would particularly like to see this kind of
highlighting are:
   display of matching delimiters (instead of doing the cursor bounce)
   current match in searches and query-replace
