Sorry if this has been mentioned before... I have been looking for 
related questions without success yet...

I have a problem "forcing" a window95 box to send 8 (or less) bpp rather 
than its true bpp (16).  Here is the command (note: I have tried both 
"8" and "256" as the parameter for the -depth switch.  It happily accepts 
both - if I put something silly in there like "50" it complains and halts 
the process startup.):

/usr/local/vnc/vncviewer -depth 8 -passwd ~/.vnc/passwd XXX.XXX.XXX.XXX:0 &

Here is the console output:
/usr/local/vnc/vncviewer: VNC server supports protocol version 3.3 (viewer 3.3)
/usr/local/vnc/vncviewer: VNC authentication succeeded
/usr/local/vnc/vncviewer: Desktop name "devo"
/usr/local/vnc/vncviewer: Connected to VNC server, using protocol version 3.3
/usr/local/vnc/vncviewer: VNC server default format:
16 bits per pixel.
Least significant byte first in each pixel.
True colour: max red 31 green 63 blue 31
            shift red 11 green 5 blue 0
Using perfect match truecolor visual, depth 16
Creating window depth 16, visualid 0x20 colormap 0x2c00001

Any thoughts?  I'd like to kick it down as much as possible (maybe 
even 4) for performance reasons.
