Great website for getting those antenna's, I personally have one in my house for my wireless connection.
And in theroy it would be very easy for someone to do what they are talking about, with a little electronics experience and software experience. But i agree with what was said earlier how lazy can some people be. I personally like my all mech guns, to me it seems like more sport to pull a mech trigger then to "click a mouse", but dont' get me wrong, either gun you use require a great deal of skill to play the game. i just like my mech guns a little more.
