You mean a couple of these?  http://www.photonlight.com/index2.html 
(They even make an infrared one too!)

Damn! Should have kept my mouth shut. 

Now I guess I'll have to leave them at home with my Leatherman Micra and my 
nail clippers :)

Depends on the overload failure mode.  Many SS camera will simply appear to 
be full white/black on overload.  Same as a malfunction.

Jamming the camera or overloading it is itself a tell.

Knowing the exact location and geometry of a camera lens makes it 
feasible to spoof the scene by placing a fixed image below the camera. 
Unless the camera has a zoom, which is unlikely, a simple affine 
transformation of a real "lap" is enough. Make it of a  lap covered with 
a blanket and then even the lack of movement will not be a tell.

A less observable jamming means is to just bring a key chain penlight 
aboard and aim it at the light.  If the light has a suction cup mount it 
can be mounted to the arm of the chair.  For more clandestine use a two 
position switch on the light could activate an IR laser/led, shining 
through the same lens, for light/dark cabin situations.

I would suspect that the engineering for this has been well developed for
years - it seems a natural extension of the habit of some national carriers
(Air France is the one usually pointed out, but one suspects they are not
alone) of wiring first class seats for sound, for purposes of industrial 
espionage.

Extending the capabilities to all classes, and to video (need to read those
negotiating postions on lap top screens, after all) seems a natural step.
Once again, terrorism is used as the justification for the further removal
of the right of privacy.
