Hello, I'm a High school teacher, and I need advice of what app to buy so I can control my laptop at school when I do PowerPoint(control slides, etc.), and look at documents. Would Jaadu work? One problem, if it is one though, I'm not sure, but there is no wifi network at school and no way to set one up that would be connected to internet, due to school's configuration of the network. I do have an Airport extreme at home though that I could connect to just the laptop if that would do anything. Any help would be greatly appreciated, I tried to find a topic on this but couldn't find one, if there already is one please lead me to it, I really would appreciate help with this because it would be immensely helpful for me. P.S. I wasn't sure where to post but figured here would work.
