Three good but not top of the line nVidia cards (the 8600 GT) in a  
$2000 box would give you the possibility for six screens, and a lot of  
software, including Director (not sure about the newest Flash),  
Processing, Jitter, and I think VVVV would let you send an application  
across all of them. That said, the nVidia control software would  
theoretically handle it if your content is composed to go across all  
of those monitors.

What's the content being pushed onto the screens? Is it all passive-  
can you make a giant rendered movie file to play in the space, or it  
is interactive content?
