Ingredients:
* mplayer -input file=<fifo>
* support for obtaining the time of the currently playing file
  (I think this may be missing in mplayer, but easy to add)
* a local program that couples the FIFO with the network
* a remote program (possibly a central server) that resyncs
  the video streams of all mplayer instances connected through
  the daemons using commands mplayer accepts over the FIFO.

Especially useful for resyncing are "speed_incr 0.01" /
"speed_incr -0.01".
