You'd need a way of knowing exactly what the laser is hitting otherwise, it would be hard know whether you're focusing on a person or just over the person's shoulder, for example.
We purchased a laser rangefinder for our robot. It's fancier than what you're describing since it does 180 degree sweeps. It cost $9K. Even if the problem of knowing what one is focusing on is solved, I have to wonder if the cost would be prohibitive.
Maybe I'm not understanding the question here, so I'm sorry if this is off base but: Let's say I want to do something (anything) with a laser. I can point the laser at an object, but if I never notice was has happened as a result of my pointing the laser at the object, how can I hope to draw any conclusions from this experiment?

. The point about shooting from the hip with preview -- IMO is from point and shooters ? which is ok for everyday shots--but when you look through viewfinder of D30 at long range with center point spot focus and you see the ss and f stop in the viewfinder and clarity of what you're shooting -- then one can understand the need for an eyepiece to shoot in focus high quality pics at long range. When 3.4 meg RAW files are converted to ~ 20meg 16 bit tiff files ? and you can adjust and recover settings with RAW ?then folks will understand quality. If I had it to do over again, I'd skip the 505v, I think I spent 1300 with extras in Feb of 2001. 1940 buys the D30 box from Delta. If I didn?t have extra money, I?d buy one lens ?50mm f1.4 for $340 ? one of the sharpest lens in the world-- and shoot with MD $270 for many months until I had enough money to buy the rest?but what the $1300 and this forum taught me was ? I wanted more with more quality.
