Actually, I tried to take a shot with my digital camera on a tripod, pointing toward Crux with the laser pointing at Alpha Centauri, with an exposure of 30 seconds. The laser did come out, but wasn't as bright as I thought (mine is only 5mW though). My intention was to try taking an exposure of say 30 seconds while the scope slews from one point to another, but with the feint trail left without the scope moving, I think it would be difficult to get the result I was after.
So yes, you will see it! I guess that is why they are frowned on at dark sites, especially when people are imaging.
