I wrote a little application that runs on rr flash skins.. You can change the size , startup position and you can get it to change skins , embed apps from within RR, so say you are watching video on the front screen, you can have a button that sends this video screen to my app.. have a look at this thread and the little vid I did. You can also add buttons to my app in flash which will be sent to road runner.. remember this isnt just a second screen, its a completely different app, so can do much more
