At the expo 2000 word fair I was maintaining hardware of something doing  
exactly this: In-sync playback on multiple machines. It was in 2000, so it  
was proprietary software running the players on windows and one extra  
machine used to keep the others in sync. The resulting video spread over  
15 large plasma displays in a row. Doing something like this by means of  
the VLC or XDMX proposal would mean to play a single video with a solution  
of about 28800x1080 pixels. I think that would need quite a fast processor  
and a considerable bandwith. If this large video is first chopped in 15  
smaller videos, the player hardware requirements would be somewhat easier  
to meet.

That's why I would prefer trying a sync mechanism. The "speed_incr" method  
sounds reasonable, that would be the first for me to try if I got the time.

Thanks!
