If I understand that part of emacs (you speak of the ``fringe'' btw),
there is little chance to do this (and Simons idea of indicating
encryption state in the fringe). The only possible pixmaps in the
fringe seem to be coded in C and are:

* line is wrapped (that \ replacement in the right fringe, the same
  thing horizontally ?mirrored/reflected?
* mode a -> arrow as replacement for $ when overlong lines are not
  wrapped (how's that mode called?) and again a ?reflected?  version
  for the left fringe
* the triangle used in debuggers (graphical replacement for the
  overlay-arrow-bla) and of course recent gnus' summary buffer.
* I thought I'd remember 7 glyphs...where's that source CD...can't
  find it...
* it's in something like src/xdisp.c...

I didn't read it carefully, so

please prove me wrong
