I don't know if syncing the videos would work because of playback issues over time but the aquarium pages sync their clocks every second just asking the server the time (demo time not wall time) over web-sockets and then subtracting 1/2 of the time it took to get a response. I suspect the technique works better for time based animations than video since video require seeking to change the time.

This is used behind most products, software, and protocol suites in the real-time media space.
