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. Mike
