There will always be some delay, but how much depends on a number of
factors. Web CAM takes time to capture one frame, then the frame (or part
of) has to be transfered to the computer and moved arounnd internally
through the OS and the application. Hence delays - if the image is
tranferred over a network more delays pile up. To get low delay video and
sound, cheap hardware, and generic software applications are not going to
be the answer I'm afraid.
