  Right.

  (i) how to customize the look of the scanner dialog

  Right and I think this is not a concern of SANE, but of the higher layer
  that is TWAIN/Linux. All that sane needs (and already supports) is a
  means to describe that option for automatic dialog generators, which
  aren't expected to make it look as pretty as a custom one.

  The SANE method is similar to (but more general then) the ISIS method.

  (ii) how to provide an "escape" or "pass-through" mechanism that
  permits for more extensibility (and how to do this without
  completely breaking interoperability)

  Right. SANE has already got that (to a degree) but only lacks an improved
  means of sending different image formats. I believe a mechanism was proposed
  in the last big discussion that supported this in a way that did not burden
  generic applications.

  In a nutshell, a new well known image format type was discussed, and the
  SANE driver requireded to support a small subset [grayscale, RGB] in
  addition to any other formats it adds. Simple and elegant. I think we
  all agreed it was nifty, and will certainly accommodate the needs of
  any scanner I can think of, without complexifying things like xscanimage.
