I really doubt that it could "see" the dot from any useful distance,
BUT...
Shine a laser at a bicycle reflector and you do get a pretty bright
return (with a wide angle of return). In a dark room it just MIGHT be
able to pick up that reflection. I want to play around with it some,
and if it works I want to build a robot that will scan a room looking
for reflectors that I place and go "tag" each one.
I think it'll be pretty neat to hear the robot moving around the dark
room and every so often see the laser turn on and scan for a target.
