Python and webcam capture delay?

[jack catcher (nick)]

Hi,

I'm thinking of using Python for capturing and showing live webcam 
stream simultaneously between two computers via local area network. 
Operating system is Windows. I'm going to begin with VideoCapture 
extension, no ideas about other implementation yet. Do you have any 
suggestions on how short delay I should hope to achieve in showing the 
video? This would be part of a psychological experiment, so I would need 
to deliver the video stream with a reasonable delay (say, below 100ms).
