Donnot know mac details. For msWindows, I know programs like webcam 
stuff have a kind of direct access to the display hardware. Vnc is not 
capable of capturing this data and hence, cannot show the contents.

For Unix X11 I know there are applications that show on remote displays 
and hence can show in vnc-sessions as these applications donnot direct 
access to display hardware.

As macs have a native and optionally an X11 display, you might be lucky 
if you try the X11 way and find/use an X11 application that shows the 
display.

On the other hand, if you want to show video contents over a network, 
there are other protocols and programs to use. the most relaxed one I 
have seen is a webcam that frequently dumps a jpeg picture in a 
directory. This so happens to be used in a webpage that has an automatic 
update of roughly the same frequency. Not enough for video, acceptable 
for the oldes webcam use in the world: scanning if there is coffee in 
the pot or ot.

As you are asking a vnc group, find attached a small 
'vnc-server-application' that shows a clock in a vnc-session. Maybe 
there is a developer out there who writes an application that shows the 
webcam data.
