IPad apps

Can you move around the screen and a spotlight would shine wherever the mouse was ? Is there a way to do that on the iPad?:

GoTalk app -if you scroll to the bottom of the settings menu there is a place for " Experimental Features" and you can choose "Show Touches When External Display is Connected"

Pictello also have this feature within the app. It utilises Presenter Touch. This is a trademarked product, so maybe other developers
can buy in this feature for their own apps. I'm not certain on this, but I think Presenter Touch is also built in to Proloquo2Go.
