What if an intruder tries to steal your ZM server while your away? This could be an annoying deterrent Provided someone figures out the protocols and how to use ZM's motion tracking to aim the thing.
Yes, that would be fun. Someone in the office where I'm working at the moment has one of these on his desk but I've not seen it fired in anger yes. I suspect it wouldn't be much of a deterrent to a determined perpetrator though
