Hardware will work. We used a VGA splitter to run a CRT and projector in 
parallel. There's probably similar hardware for HDMI, and surely for 
composite video, component etc.
It may even be possible to daisy-chain component video on BNCs to 
multiple displays providing that the termination resistor is removed 
except from the end of the chain.

For a system with a dual-head card such as Nvidia quadro etc, I'm not 
sure. I think some of them have a dual mode. We've always wanted 
independant displays, or merged/xinerama mode, but I think I remember 
seeing console text scrolling on two screens at startup once.

In passing I note that some older dual-head cards don't have full 
graphics acceleration on both heads, which can lead to some weird 
effects. I've seen a movie window straddling two displays in merged mode, 
with the right half black and the left half playing normally.

Other crazy ideas - run the DVD from a streaming server and run multiple 
copies of mplayer, one on each monitor.
