AV share

Problem
Schools are hanging big flat screens on walls for students to share. Open source hardware and software can be used to share monitors, LCD projection systems, web cams and speakers in the room. How can this be done?

Demo

 * video

Next Steps

 * Can not display video ... video plays so slow, looks like a slide show. Need to isolate the problem to the network (did have problems with raspberry negotiating hard wired ethernet connection speeds with schools gigabit ethernet hubs) or to the raspberry.
 * Can not see the mouse ... have to get out of seat and wave a stick at the monitor or use laser pointer on one monitor (not all of them) to point
 * Can not hear anything .. possibly use PBX software asterisk to share sound ... raspberries have sound ports that could be connected to speakers
 * Can possibly hook usb web cameras to the raspberrys to enable display on any monitor
