OK, Thanks.  It's somewhat clear.  One can
twist into a pretzel thinking about it.  I just
tried the viewer with -truecolour and depth
24, but still getting 8bpp truecolour.  I'm
assuming that the sun box hosting the viewer
is not capable of 24-bit true color (maybe it's
using its color map to emulate 8-bit true
colour, if that's possible).

I got the idea of what you described re. both
the vncserver and the host sun box just be
capable of 24-bit true color to realize such
visual, but it seems odd that the capability
of the host sun box should come into play
at all, since it is really only a virtual desktop
i.e. doesn't even have to be associated with
a real graphics card or display.  In principle,
the software should be able to treat the
graphic information in the same way as if
there was a 24-bit true colour visual, and
convert that data to whatever format is
requested by the remote viewer.

Anyway, you've done quite a bit to cast
light on it, and I don't expect you to provide
an X-tutorial (or graphics tutorial) on line.

Thanks.
