As a personal anecdote, I saw Arjun and Jason present the latest developments in UCSniff at ToorCon 11 and was awed at how smoothly the features worked, and the power of the video manipulation features.

Jason and Arjun's demo used a Cisco IPTV camera for video surveillance, watching a bottle of water.  First, they established MitM (I believe through ARP spoofing) and saved a segment of the existing video traffic.
 Then, they blocked the actual stream from the camera to the receiver and fed the receiver the old video footage instead, causing a momentary blip on the video monitoring side.  Then, they stole the bottle of
water, while the video monitoring system happily replayed the old footage.

It reminded me of the A-Team episode where Murdoch climbed into the ceiling and lifted a ceiling tile from above, then used a Polaroid camera to take an instant picture of the room from the perspective of a
ceiling-mounted camera.  Then, he taped the photo to the front of the camera so the security guards saw the same view while the rest of the team went through the room undetected.  Well, except that Arjun and
Jason's work was much cooler (and a lot less Polaroid-hurry-up-and-develop-waving-action).
