Something similar to Watchout or Datatone Systems ... Not sure what you understand by 'frame synchronization': Equalizer supports software and hardware swap buffer synchronization, and synchronizing the video frames is just a matter of using the correct timestamp or video frame. The timestamping is easy to implement using the FrameData mechanism. > Could Equalizer help on playing in synch a video wall splitted over N > computers ?

This is true, but it doesn't mean that you can't make use of it for video. 'Collapsing' 3D into 2D is trivial, and OpenGL is often used for 2D stuff nowadays (eg the OSX desktop compositor). The basic design question for an 'eqVideo' for me is: What is the video source - the application process or a file. Or, put otherwise, is the application multicasting new video frames or are the render clients accessing the video directly. The first approach is more flexible when it comes to the video source, e.g., a webcam, but does need some care to get the proper performance since the video is sent over the network. I don't see anything Equalizer can't do what other video-wall solutions can. It might need some more work since the application does not yet exist, but the the 3D aspect also gives you more flexibility. One could place video 'billboards' in 3D space and create easily a VR experience.
