A touch of geni..

Two touches :)

Great idea for a CU_SeeMe plug-in

I use the CameraMan program (Mac) for making a film of whatever is
frame-selected from the screen.
My MacIIfx can keep up.

But of course it saves to a file, and (video)pipes ...dunno if such a thing
could be constructed.

BTW just something analogue;
Having a QuickCam and no sampling-board . Putting the QCam in front of a
video-monitor connected to a fancy auto-focus/zoom/whatever camera gives
some extra features if you need them. Ah.. scanning interference (flicker),
maybe a LCD tft viewfinder (the ones that you can watch from many angles)
can do the trick (with a extra positive tinker-lens to the QCam) .
I would hide this set-up in a box, just in case funding-control might drop in.
