While investigating some hidden features, I realized that a new project was emerging from my brain: ScreenStudio!
ScreenStudio is capturing your desktop with your webcam overlayed and is able to broadcast to any RTMP server (Youtube Live, Ustream, Twitch...). If you don't want to broadcast, you can record locally into a file.
ScreenStudio is not WebcamStudio. It lacks all the "live" features, but does it does one thing very well: Broadcast your desktop!
