I am straying a little ot here for a moment, but you guys are mentioning 
bouncing lasers off of objects in space.

what is the legalities to bouncing lasers off of satellites. i know here in 
the usa if you shine a small laser in the sky and a plane see's it you will 
wind up getting a rectal from homeland security.

it happened to a guy in plainfeild nj (maybe 2 years ago) not too long ago.

he was playing with one of those laser pens (kind you get from wal mart) in 
his backyard with his kid. shining it in the sky and such. by morning he had 
several 3 letter agencies parked on his front lawn asking him all sorts of 
question. it made the regional paper as well.
apparently he lit up the cockpit of a passing passenger plane.
