I'm not sure I understand the distinction.  For example, if I pipeline a 
series of camera images
at the desired frame rate into a component that converts a sequences of 
frames into a video
stream, then I achieve the desired result right?

I imagine that the video streaming component would surely be very 
portable, but the video
capture would tend to be O/S and hardware specific. 

Maybe what the world needs is a set of webcam drivers wrapped up into a 
single platform-
independent PIL compatible python module, that could then be wrapped 
into a Kamelia
component.  Anyone else interested in such a project?  I can't believe 
such a thing doesn't
already exist.
