I'm working low priority on a tool that could do the job (event
triggered video sequencing), but it's far from being usable - check
xjadeo and gjvideotimeline SVN-devel-branches on sourceforge and stay
tuned for video-jack...

You can already do sth. like that with the xjadeo remote control, but
xjadeo does not pre-cache video (the xj5-branch and gjvidetimeline do),
but you can change the video-file(s) and video-file-offset during
runtime and use JACK-transport to start/stop the show.

mplayer does provide low latency, caching and double-buffering. If you
only want to trigger sequences: just script it,  it can even read simple
EDLs and is quite flexible. - but you can not sync it to some external
app, only trigger it to start/stop.


The dual-head setup depends on your grafix hardware not the software.
many chipsets only allow accelerated video only on one video-pipe
(usually the built-in on laptops) - you can always render something on
the 2nd screen in RGB (check mplayer -x ..) but it's probably going to
be slow..
