I think we should add separate keys to drivers licenses that authorize
one to purchase plumbing components, red meat, optical components,
electronics devices, ammo, porno...just add it to a 2D barcode. It would
not be any inconvenience at all.

It looks like to get any significant distance you would want substantial
power. Then a possible downfall would be "unsafe use of a laser." I
think this is what was used some years back when people started playing
around with laser eavesdropping devices. It makes no difference whether
or not the power levels or use are actually dangerous: in the minds of
most :

#define LASER \
( Spectre + evil_conspiracy + guys_in_labcoats + flash_fried )

Call lots of optics guys who would show how misalignment could cause
stray reflections, eye specialists to talk about retinas etc...still a
good idea for *local* neighborhood. Have you got any specific info on
what is already commercially available? 

BTW - It would probably be easy to map one of these nets using an
appropriate imaging device because there would be a number of sources of
stray light. Turn on the right camera and the spiderweb shows up. I see
a plane going overhead at night, a little upwind, dispersing a fine,
*harmless* dust, storing away a few frames of data as the dust drifts
across the landscape...

You could easily cut a coax into the turf bewteen two houses. The
hardest thing to track or shut down would be a distributed system that
had some unpredictable bridges in it. Build a FrankenNet - sewn together
from all sorts of obscure pieces.
