I don't think the saftey mechanism you are talking about is possible without huge expense. I just had an alarm fitted which included the function you are talking about. I can remotely close all windows. However, I have to keep my finger on the button. The reason for this is so that I don't let the windows close on anything or anybody. Electric windows are merely motors with a start and end point. There is no feedback during the closing operation from the window itself. Will prb get a lot of people disagreeing with me but I thought I would try and answer.
