You are right, the only option I used is the fullscreen one. I used it 
with xine, but the same apply for vlc, .... Could also be useful for 
picture viewer, but you are right, I wouldn't want it for other 
applications.

I don't know what's your idea behind the "script taking care of setting 
the fullscreen" ? Do you want to use "Special Window Settings..." menu 
for movie players ? If it works for setting a fullscreen spawning all 
monitors, that sounds a reasonable option for me.
Or maybe you are thinking about something else ?

Anyway, no need to say that if there is new feature to play fullscreen 
movies on several monitors, user should have the choice to enable or 
disable this feature (I don't think all xinerama users want to watch 
their movie across all their monitors ;-))
