Remote Control

When using other presentation tools I tend to have two screens, one for the presentation and a second, that I can see that contains speaker nodes and possibly shows the next/previous slide. The font size used on the main screen should be rather large while my screen can be a lot smaller. It would be amazing if I could connect to a currently running presenterm presentation and both send controls and get information from it. i.e. current screen/next screen/previous screen; in a given resolution. presenter notes for each screen, total number of screens, running time, etc.
